SCRAPBOOK SERIES 


The four scrapbooks in this series cover the period 1901-1904. They 
contain clippings from newspapers, popular magazines, and technical 
journals, along with other printed material. Two scrapbooks from 1901-1902 
pertain to the development, testing, and manufacture of Edison's alkaline 
storage battery. The one selected book includes articles by former Edison 
employee Arthur E. Kennelly and by electrochemist Eugene F. Roeber. The 
other two scrapbooks (not selected) contain material regarding the 
International Correspondence Schools—an organization based in Scranton, 
Pennsylvania, which promoted Edison's phonograph for educational use. 


In addition to these items, the Scrapbook Collection in the Edison 
National Historic Site archives has several books from the period 1899-1910. 
These contain souvenirs, postcards, and holiday greetings collected by Mina 
Miller Edison and others. Two undated scrapbooks contain the original labels 
from Edison's mineral cabinet, indicating the names and origins of the 
samples collected. A finding aid to the archival collection is available.

Scrapbook, Cat. 44,496 


This scrapbook covers the period January-December 1901. In addition, two loose items 
from September 1902 have been inserted into the book. Included are articles about Edison's 
alkaline storage battery by former associate Arthur E. Kennelly and by electrochemist Eugene F. 
Roeber, along with other battery-related clippings from the Electrical Review, Electrical World and 
Engineer, Western Electrician, and New York Tribune. 


Scrapbook, Cat. 44,495 [not selected] 


This scrapbook covers the period February-August 1901 and relates to the development, 
testing, and manufacture of Edison's alkaline storage battery. The clippings are primarily from daily 
newspapers, but some are from technical journals and popular magazines. Included is material 
pertaining to Edison's storage battery factory at Glen Ridge, New Jersey; his visit to the Sudbury 
region of Ontario; and a conflict with the General Electric Co. over the use of the battery. 


Scrapbook, Cat. 44,493 and Cat. 44,494 [not selected] 


These two scrapbooks probably cover the period 1903-1904, but some of the items may 
be from earlier or later dates. Included are clippings and printed promotional material relating to 
the International Correspondence Schools (I.C.S.)—an organization based on Scranton, 
Pennsylvania, which promoted Edison's phonograph for educational use. The material was 
apparently collected by Nelson C. Durand at |.C.S. before he joined the National Phonograph Co. 
in 1905 as manager of the Commercial Department. Several items from these scrapbooks can be 
found in the Primary Printed Series.

bn indefinitely, with a simultaneous depression of the temperature 
pf the expanded gas down to the theoretically absolute zero of +273 
legs. C. at which there would be no heat left in it, The ratio of the 
working range, to the total ideal range of temperature down to 
Absolute zero, represents the thermodynamic efficiency, and the limita- 
tions of the heat engine, It would seem that any heat engine or energy- 
converting apparatus that involves a rejection of heat at a lower tem- 
perature must be subject to this limitation and disastrous waste. 
The question has therefore often arisen whether the energy can- 
not be extracted from coal without having recourse to the thermo- 
dynamic process, and, therefore, without having to pay such heavy 
tribute to the absolute temperature of 300 degs, C., or 300 degs. above 
absolute zero, at which we happen to live, and below which we are 
iw unable to carry our expansion. 

If, for example, coal were converted into coke, which conversion

combination between coke-carbon and oxygen could be liberated in 
B the electrical circuit of the apparatus, This would represent the direct 
generation of the energy of coke-carbon into electrical energy. Un- 
fortunately, however, carbon refuses to behave like zinc and burn in 
a voltaic cell. The only known means by which carbon could be 
made to give out its energy in a voltaic cell, in competition with the 
use of coal in the steam engine, is by the formation of either carbon 
monoxide or carbon dioxide; in other words, the same oxidization 
which yields the energy of carbon in the process of combustion must 
take place electro-chemically. The oxygen for this purpose must be 
obtained from some cheap elec- 
trolyte containing oxygen, and 
fay cannot, so far as is known, be ob- 

tained from the atmosphere direct- 
ly, In other words, it is necessary 
8 to rob an electrolyte of oxygen in 
order that the carbon shall com- 
bine with it electrolytically. If the 
oxygen of the electrolyte were but 
feebly held, that is to say, if the 
electrolyte consisted of a chemical 
combination with oxygen so un- 
stable as to require but a negligi- 
bly small amount of energy to tear 
the oxygen away,and if, moreover, 
the substance or substances with 
Awhich the oxygen was unstably 
M linked were capable’ of entering 
into combination with the other plate of the voltaic couple, with but 
Mlittle absorption of energy; then it might be possible for the voltaic 
ell to work with a power output theoretically approaching that of the 
combustion vatue of carbon and oxygen. The union of carbon and 
¥ oxygen in the cell would take place without sensible elevation of 
MH temperature, the clectrolyte would give up its oxygen for the forma- 
fa tion of carbon dioxide, and the products of the cell would have to be 





















fresh electrolyte. All this requires the existence of an electrolyte 
possessing the properties of small chemical stability, together with 
the capability of forming suitable chemical combinations at botl 
MM plates of the couple. Moreover, the electrolyte must be so abundant 
as to be very cheap. 

Unfortunately all the electrolytes that are abundant are very stable 
combinations, which require a large amount of energy to tear the 
oxygen away from them, and if, as commonly happens, the energy 
H required to abstract their oxygen is greater than the energy which 

carbon will yield on combining with their oxygen, it is evident that 
& the voltaic cell so constituted would not work. The amount of energy 
which is necessary for the chemical disunion of oxygen from all the 
ordinary electrolytes is fairly well known by thermo-chemical meas- 
turements. An examination of thermo-chemical data confirms the re- 
sults of the very large amount of experimental enquiry made during 
the past century, and leads to the conclusion that there is no cheap 
electrolyte available for the burning of carbon in a yoltaic cell, at

chemically eliminated in some continuous manner, to be replaced by" 


y 


Turning now to the voltaic cell worked at high temperatures, in- 
stead of at ordinary temperatures, although the prospects from 
thermo-chemical data seem equally unfavorable, yet there is some 
hope of success in this direction, if only from the fact that there is 
less experimental knowledge of hot voltaic cells than of cold voltaic 
cells, and there is always hope so long as any reasonably available 
combination has been left untested. The electrolyte would now be a 
fused salt instead of a solution, and must give up oxygen to the car- 
bon for the production of carbon monoxide or dioxide. The remain- 
ing constituents of the electrolyte must be suitably provided for, and 
eliminated at the opposite plate, without serious loss of energy, 

The hot voltaic cell is complicated to some extent by the introduc- 
tion of thermo-electric phenomena, which inevitably accompany the 
contacts of dissimilar matcrials at markedly different temperatures. If 
the cell is a mere thermo-clectric couple, it must do work in the circuit 
by receiving heat, at a high temperature, at one contact, ‘and reject- 
ing heat, at a lower temperature, at another contact, thereby coming 
under the thermodynamic law of temperature limitation, just as does 
a heat engine, besides being subject to additional limitations imposed 
by purely thermo-electric conditions. Consequently, not only is the 
thermo-electric method of obtaining energy from carbon, by allowing 
its combustion heat to operate thermo-clectric couples, likely to be a 
failure in competition with the steam engine, owing to the tempera- 
ture range limitation, but any real voltaic action in which carbon is 
oxidized in a hot electrolyte can succeed only in spite of, and not by 
reason of its accompanying thermo-clectric actions, 

In other words, it would scem that a hot voltaic cell can only be a 
successful competitor with the steam engine on account of its voltaic 
action, and such thermo-electric ‘actions as inevitably occur therein 
must be wasteful for the same reason that the steam engine is waste- 
ful; namely, because the tempera- 
ture range, instead of being be- 
tween the high temperature and ab- 
solute zero of temperature, is ac- 
tually between the high tempera- 
ture and a convenient moderate 
temperature, While, therefore, the 
prospects are not encouraging for 
the production of a hot voltaic cell- 
burning carbon, yet there is hope 
that it may be found, whereas, with 
the cool voltaic cell, the case seems 
to be almost hopeless for the near 
‘future, 

If the energy of burning carbon 
with oxygen cannot be liberated 
electrically in a direct manner, as 
above outlined, yet it may be pos- 
sible to use its chemical potential energy to perform purely chemical 
change in other combinations, and use the resulting products of that 
chemical change for the final development of electrical energy in the 
circuit of voltaic cells. Such exchanges of chemical energy at high 
temperatures are not subject to the thermo-dynamic law of tempera- 
tures, although incidentally much heat energy is usually wasted by 
the furnaces in which such substitution takes place. Theoretically, 
the exchange of chemical energy from carbon to some other sub- 
stance in this manner does not necessarily require a wasteful expen- 
diture of heat, and it is conceivable that the furnaces in which the 
exchange occurs might be made so nearly heat-tight, by gradual im- 
provement, as to waste but little energy. 

Such indirect processes of obtaining energy from carbon are 
already in use and are illustrated in the ordinary voltaic cell burning 
zine. ‘The zine is originally taken in the form of oxide, and heated 
in a closed furnace with carbon; the energy necessary to tear the 
oxygen from the zinc, or reduce the metallic oxide to the metal, is 
supplied by the energy of combustion of carbon with the oxygen, 
and if the retort could be made heat-tight, and the waste of heat in 
raising the temperature of the active substance prevented, the energy 
of carbon would be transferred to the zinc in a fairly considerable 
proportion. Owing, however, to the fact that in practice very con- 
siderable thermal waste docs occur, the metallic zinc, when prepared 
for the voltaic tell, carrics but a very small fraction, usually less 
than 1 per cent of the energy originally possessed by the carbon used 
in the process. Moreover, the labor involved in the operation of ex- 


changing the energy between the carbon and the zine increases the 
ee 8 atenenfaean ac fe walt kenawn. that the voltaic 


eit. 





























































battery employing zinc cannot possibly compete with the steam engine 
as a developer of power. 

In this indirect method of transferring the combustion energy of 
carbon to some substance capable of use in a voltaic combination, 
there is probably much more hope of exceeding the efficiency of the 
steam engine, than in obtaining the energy by a direct voltaic method, 
if only for the reason that the experimental field is so much more 
extensive. If, however, a substance or combination of substances 
were found in which, with the aid of carbon, combustion cnergy in an 
improved voltaic cell could be developed so as to attain a final effi- 
ciency exceeding that of the steam engine, it might readily happen 
that the cost of the labor involved in the supply of the active sub- 
stance and in conducting the process might be prohibitively great, so 
that unless the substance were very cheap and the process of energy 
exchange and subsequent voltaic release very simple, no commercial 
realization could. be expected, 

There are consequently two broad avenues in which improvement may: 

“be looked for in utilizing the energy of coal. One is by improving the 
heat engine, and the other is by finding a suitable substance to burn in 
the voltaic cell, either hot or cold, transferring the chemical energy of 
carbon to that substance by purely chemical means in a retort as 
nearly heat-tight as possible, 

So far as the heat engine is concerned, it is reasonable to expect 
improvement inthe apparatus whereby the energy thermodynamic- 
ally convertible may be better conserved, or the efficiency of the 
machine improved, when debited with all the energy that its temper- 
ature range will permit of being converted from heat into mass 
motion. But with the modern steam engine, if these wastes were 
entirely prevented, the efficiency would still be only about 20 per 
cent, and the real difficulty lies in the range of working temperatures, 
What is needed is a greater range of temperature, a lower tempera 
ture of the condenser, and a higher initial temperature of the work 
ing substance, the latter requirement being much the more important 
of the two, In the case of the steam engine, this means higher steam 
-Pressure, and improvements during the past century have been 
steadily made in this direction. A greater difference of temperature 
in.one and the same engine, however, tends to increase the thermal 
waste by leakage conduction from the hot parts to the cool, and so 
to diminish the relative actual efficiency. This has been, to some ex- 
tent, overcome by coupling three or four seperate engines to one com- 
mon driving shaft and expending the steam successively in the suc- 
cessive engines, thus producing the multiple-expansion, compound 

. engine, The limits of temperature and pressure elevation seem to be 

almost reached for the present in this direction, partly owing to the 
increased difficulties in lubrication at high ternperatures, 

Tn the gas engine, however, the initial temperatures are consider: 
ably higher, and for this reason the thermodynamic efficiency of gas 
engines attains nearly 30 per cent or is considerably above that of the 
steam engine. All that can be said for the future of heat engines is 
that any marked improvements in their efficiency must come from 
an increased range between the limits of the initial and final temper- 
atures, whether this be effected in one engine, or in a plurality of 
associated engines. Improvement in lesser degree may, of course, be 
expected from the diminution of heat wastes in boiler and engine, as 
well as in the reduction of mechanical friction. The steam-turbing 
principle, if successfully adapted to large sizes of engines, would in- 
troduce a great simplification of parts, reduction of weight, with, per- 
haps, some dimintution of these losses, But the steam turbine must be 
as much limited by the temperature range, as the ordinary recipro- 
cating heat engine, 

Apart from the solution of the problem by improvements in feat 
engines, or by the discovery of a suitable working substance in the 
voltaic cetl, there is always the possibility of finding some new me- 
chanism by which the heat energy of carbon atoms can be converted 
into the energy of mass motion. We are still so profoundly ignorant 
of how the energy of carbon is stored relatively to that of oxygen, 
that a discovery of the hidden mechanism of the storage principle 
might lead to a discovery of a new means of releasing it. In other 
words, there is something in a Iump of carbon in conjunction with 
a lump of oxygen, which corresponds either to a bent spring or to 
the motion of the gyrostat, All we know is that when the two sub- 
stances are brought into sufficiently intimate contact, with the aid of 
a high temperature, either the spring is released, or the gyrostatic 
motion is arrested, with the production of jostle-energy among the 
molecules of the substance, or of that particular kind of rapid oscil- 
latory molecular. motion which we assume heat to be. Tt is conceiv-

Light without Heat, 














By Pror, R. A. Fessenpen, 


PPARENTLY the most self-suggesting way of getting light 
without heat would have been to have developed eyes which 
could see afl the rays. But with an extremely aggravating 

indifference to the waste of grey matter thereby to be entailed upon 
their descendants, flabby one and backboned one went placidly along, 
developing eyes which would only respond to a quite limited range 
of vibrations, And if this apparent lack of business foresight had been 
pointed out to any particular specimen of wiggling iniquity, he might 
possibly have replied, “Do not tinker with development. In years to 
come, one with a backbone will call your attention to the fact 
that, ‘in the long run, the will of the people is, for the people, bet- 
ter than that of the wisest individual. If we developed such eyes for 
you, they would not be ‘of use, for what you saw with heat rays , 
would be blurred, and’ ultra violet rays don’t go very far. And be- 
sides, as regards X-rays, with the morality of the community in such 
a rudimentary state, I have serious: objections to my neighbors being 
able to sce when I have anything extra good to eat inside me. Con- 
sider our economical friend, the firefly, who serenely oblivious of the 
ineterman’s threats to turn off the gas, titillates at will his abdomen 
up to any desired candle-power, and go and do likewise.” 

But we have been a long time trying to do likewise. x 

How much the sky meant to our predecessors, we can never know. 
Sometimes a long stretch of camp life goes far to give one a faint 
conception and to make him realize, that as we have extended our 
knowledge, we have contracted our firmament. No one now loaks up, 
and we have forgotten the array of the stars, 

From resinous knot to the flame of burning oil cannot have been 
a far step, but for more than forty centuries (how much longer 
we do not know) we rested at this stage. And it is a wonderful thing 
to contemplate, that the generation now passing has been the first, 
since the world began, to be able to neglect the waxing and the waning 
of the moon. And since gas itself is merely a light hydro-carbon, of 
the same general nature as that used for lamps and candles, being 
thus rather an improvement in the means of distributing the material 
than a new method of lighting, we may say that it is only within the 
last twenty-five years that new methods of lighting have come into 
use, 

These may be divided into the following classes, (not fundament- 
ally, but merely for the purpose of dealing with them.) 

First—Light produced by heat. p 

Second—Light produced by heat combined with chemical action. 

Three—Light produced by chemical action. }

to be made in the first of these. hee %

~ Edison’s Work in Storage Batteries, 


Considerable interest has been manifested in the announcement 
that Edison has been working on a new type of storage battery, but 
no definite information has been obtainable concerning the same, 
While the. American Patents have not yet been issued, an English 
patent has, however, been recently granted, an abstract of which 
has just appeared in a German paper, We, therefore, give below a 
nearly literal translation of this abstract, it being the only informa- 
tion which, up to the present time, is available in this country. We 
assume that the accumulator described therein is the one—or one 
among others—on. which Mr. Edison is now working, as it’ answers 
to the description that it'is not a lead accumulator, and that ‘the 
chemical actions in it are quite different from those in the ordinary 
storage battery. tans ‘ 

In some respects the German abstract is not very clear, but the 
general principles’ of the battery can be understood from the article; 
It seems to be fundamentally a modification of the familiar copper 
oxide alkaline accumulator, for which such great claims were made 
a dozen or more years ago, and one form of which was known in 
this country as the Waddell-Entz. battery. One change seems to

greatly increased. . Edison ‘has found that very finely divided cop- 

per forms copper oxide free from water and insoluble in alkaline 

lyes, whereas with the smallest particle of solid copper present or 

upon the pressing together of the finely ‘divided copper, soluble 

hydroxide of copper is formed, Finely divided copper is artificially 

Prepared, preferably by the reduction of the carbonate with hydro- 

gen. As negative electrode, finely divided cadmium is used. This 

and the copper are in a tank of nickel or other metal, such as nickel 

plated iron, i ‘ 

Fig. 1 gives a perspective view of a plate, Fig. 2 a horizontal i 
cross-section of a pair of plates, and Fig. 3 a vertical cross-section’ 
of a cell with two pairs of plates. The plate marked 1 is made of |- 
relatively thin sheet nickel, The lower parts of the plates are con- |.:!. 
nected by insulating rods, 4, passed through the holes, 4; The: pins, |. 
5, in the holes, 5, in the upper parts of the plates are used for the 
electrical connection. On one side of the plates there are reservoirs 
or “pockets” marked, 6, for the electrode metals, : These pockets | 
are best made of perforated nickel sheets or nickel-plated sheets. 
The best method of cleaning the plates is to heat them in a closed |. : 
compartmnt to a red heat, and then reduce the oxide by hydrogen. 
Cadmium in very finely divided, fibrous and vety pure condition, is 
obtained by electrolysis of a week solution of cadmium sulphate |, 
between a thin platinum wire as cathode and ,a;gadmium sheet as 
anode, using a strong current. The deposit ae is removed 





from the cathode from time. to time, and fri the sulphate by 
washing with water. It is then filled into the ckets,” 

Finely divided copper is obtained by the reduction of fine carbon= 
ate with hydrogen. The temperature must be kept as low as the 
completeness of the reduction allows, as otherwise the density of the 3 
copper is increased too much: The finely divided copper thus ob- 
tained is poured under slight pressure into thin blocks which fit the 
“pockets” accurately. To avoid an increase of the density of ‘the 
copper-in parts, the molds must not scratch or otherwise injure the 
plates, The plates are then heated in a closed compartment for 6

or 7 hours, to not more than 260 degs, (probably centigrade), until | 
the copper is changed into the black cupric oxide. At higher tem- 
peratures the density is increased too much. The cupric oxide 
blocks are next reduced to metal electrolytically, and are then 
changed into the red cuprous oxide by charging, It would be pos- 
sible to fill the finely divided copper first obtained, directly into the 
pockets; but as it is not fibrous like the cadmium, the connection

Within the next few weeks,” a

FIGS, 1, 2 AND 3.—EDISON’S STORAGE BATTERY, 
consist in having. the copper more finely divided, ahd in the use of 
cadmium instead of zinc, The battery seems, apparently, to be iden- 
tical with an accumulator described in a Swedish patent to Schmidt 
and Junger. There appears to be a misprint concerning the volt- 
age, which is given as 44, but this is probably a misprint for 0.44, 
which would be @ little more than a fifth of the voltage of the ordi- 
nary accumulator. This voltage corresponds approximately to that, 
required by theory. If this is correct, it would, therefore, have to 
have five times thie ampere-hour capacity per pound of cell to be 
the equivalent of the lead accumulator as to ‘weight. Mr. Edison is 
understood to‘have said that he cuts the weight of the cell in two 
for equivalent work. Judging from the extract from the patent, 
Great care is necessary to have the copper extremely finely divided, 


. or otherwise it is claimed: the copper will dissolve. 


The abstract, of which the following is a translation, is from the 
Centralblatt fuer Accumulatoren und Elementenkunde, The trans- 
lation is as follows: The present accumulators are too heavy, be- 
cause much solution is required. In this new storage battery the 
electrolyte remains unchanged, so that only a small quantity of it 
is required. As ‘depolarizer, the lower oxide of copper is used; 


\that is, the red oxide. In the older cells of this general type (re- 


ferring presumably to the alkaline copper accumulator) soluble 
copper salt is said to be formed, which transfers copper to the zinc 
and thus produces rapid deterioration by local action, Efforts were : 
made to prevent the circulation of this salt by surrounding. the posi- 
tive electrode with a porous material, but these experiments -were 
unsuccessful because this material did not prevent the circulation 


“entirely, and was destroyed gradually by’ the strong, alkali A more- , 
‘over, much liquid was required _and_the resistance

for the purpose as when treated in the way just described, 

After the pockets have been filled and the plates of equal sign have 
been connected together, they are placed in a case, 7, which contains 
as electrolyte a 10 per cent solution of pure hydroxide of sodium. 
During the charging of the cell, cuprous oxide is formed and water 
is decomposed. During the discharge, cadmium oxide is formed and ;: 
water is regenerated. As only a very small amount of liquid is re- '. 
quired, it is: sufficient to place thin sheets of asbestos or another ' 
light, powerful material which is not attacked by alkalies, between 
the plates and to moisten with the electrolyte. The internal resis- 
tance is very small. The materials are not attacked, and there is no 
local action between the cadmium and the nickel. The case, 7, may 
be made of nickel or other metal, for instance iron, the interior of 
which is nickel plated. The case may be sealed for liquids, the open- 
ing, 9, being required only for the gases which are formed when the 
céll is overcharged. : i 

It may be added that not only has Mr, Edison stated that he would 
reduce the weight of the modern storage battery by one-half, but 
that he would reduce the depreciation to a tenth—to virtually 
nothing. — i

~ 


I take pleasure in bringing to the notice of the 
lustitite this evening a novel type of storage bat- 
tery, recently invented by Mr, Edison, It is well 
known that the history of the storage cell is essen- 
tially that of the lead cell, discovered hy Planté 


‘tin 18Co, in which lead peroxide is the depolarizing 


Substance, An enormous amount of labor has, in 


-{the aggregate, been expended upon the improve- 


ment of this cell in the hands of experimentalists, 
As a result of that labor, the storage battery has at 
last become a recognized adjunct to direct-current 
central stations, but it has limitations that seen, 
to withstand further attempts toward improvement. 
OF recent years hardly any success has been met 
with in the direction of reducing its weight for a 


[given energy of storage capacity without detriment 


to endurance, and this weight is the great draw- 


«back of the storage battery in electric storage-battery . 


traction, and has been the principal obstacle to its 
advance in this direction for the last 20 years, 

In practice the storage energy per unit mass of 
the modern Iead battery is from four to six watt 
hours peF pound of battery (88 to 13.23 watt-hours 
per kilogram). Expressed in another way, 2 bat- 
tery weighs from 1245 to 186.5 pounds per horse- 
power-hour at its terminals (75.5 to 113.4 kilos per 
kilowatt-hour), or, if its stored energy avdilable at 
terminals were all expended in gravitational work, 


.Ja battery could raise its own weight through a ver- 


tical distance of from two to three ‘miles (3.2 to 
48 kilometers), é 

While it is. possible to increase the energy per 
unit mass by making the electrodes very light, yet 
this is always found to be followed by a very heavy 
deterioration, Many attempts have also been made 
to perfect storage cells of the alkaline-zincate type, 
hut the great difficulty of depositing zine’in coherent 
form from the solution, as well as the lack of a 
depolarizer that shall be insoluble in: the electrolyte, 
has stood in the way of this cell's success, 

Mr, Edison set himself the task of finding a cell 


‘| which should possess the following advantages: (1) 


Absence of deterioration by work; (2) large storage 
capacity per unit of mass; (3) capability of being 
rapidly charged and discharged; (4) capability of 
withstanding careless treatment; (5) inexpensive- 
hess. 

Mr, Edison believes that the cell now shown may 
claim the advantages in a very satisfactory degree, 
The negative pole, or positive element, correspond- 
ing to the zine of a primary cell, or the spongy lead 
of a secondary -cell, is iron.. The positive pole, or 
negative clement, corresponding to the carbon of a 
primary cell, or lead peroxide of a secondary cell, 
is a superoxide of nickel, believed to have the for- 
ula NiO: The cell is therefore a nickel-iron cell, 
a name which suggests the structural material, nickel- 
steel. : . 

The electrolyte is potash, viz. an aqueous solution 
containing from 10 to 4o per cent, by weight, but. 
preferably 20 per cent., of potassium hydroxide, the 
freezing temperature of which is 20 degrees below 
zero F., or —30 degrees C, The initinl voltage of dis- 
charge after recent. charge is 1.5 volts. The mean 
voltage of full discharge is approximately 1.1 volts, 
The normal discharging current rate per unit area of 
active clement (positive or negative) is 60 milliam- 
peres to the square inch, or 80.64 amperes to the 
square foot, or 0.93 ampere.to the square decimeter, 





The storage capacity of the cell per unit of total mass 
of the cell is 1.4 watt-hours per pound, or 30.85 watt- 
hours per kilo. Expressing the same statement in 
‘another way, the weight of battery per unit of elec- 
‘tric energy at terminals is 53.3 pounds per electrical 
horsepower-hour, or 32.4 kilos per kilowatt-hour, 
Or the battery gives energy at its terminals sufficient 
to lift its own weight through a vertical distance of 





approximately seven’ miles, or 11.26 kilometers, 

The mean normat discharging power rate per unit 
mass of total cell is 4 watts per pound, or 8.82 watts 
per kilo, corresponding to a normal discharge period 
of 3% hours. ‘The cell may, however, be discharged 
ata relatively high rate, or approximately one hour, 
corresponding to a discharging power rate per unit 
of total cell mass of 12 watts per pound, or 26.46 
watts per kilo. 

Charging and discharging rates are alike; that is 
to say, the cell may be charged at the normal rate 
in 3% hours, or it may be charged at a relatively 
high rate in one hour, with no apparent detriment 
beyond a somewhat flowered electrical charge effi- 
ciency. In other words, the cet! does not appear to

be injured by overcharging or discharging, and only 
suffers in electrical efficiency under such treatment. 
The positive and negative plates are mechanically 
alike, and can scarcely he distinguished by the eye. 
They differ only in the chemical contents of their 
pockets, ‘The samples exhibited were intended for 
automobile, batteries, and illustrate the construction, 
Each plate is formed of a comparatively thin sheet 
of steel, 0.61 millimeter in thickness, in which rectan- 
gular holes are stamped so as to leave a grid or frame 
somewhat resembling a window frame, In the plate 
shown there are three rows of eight such restangular 
holes or recesses, or 24 recesses in all, Each open- 
ing or recess is filled with a pocket or shallow box. 
containing the active material, These boxes cor- 
respond to the panes of glass in the window-frame 
analogy. The panes, instead of being thinner than 
the frame, as in an actual window, are thicker than 
the’ frame, or project slightly beyond the surface 
of the steel grid. They are perforated with numer- 
ous sinall holes to admit the electrolyte, but en- 
tirely conceal the contained active material from 
view. All that meets the eye, therefore, in any of 
the plates is the steel frame and its embedded “win- 
dows” of perforated steel, 
The active material is made in the form of rectan- 
gular cakes or briquets, and one ‘stich briquet is 
lodged in. each pocket or “window pane” of the 
plate, Each of the plates therefore supports or con- 
tains 24 briquets of active material, all in. rigid 
contact with its own substance. Each briquet is 
placed in a shallow, closely-fitting, nickel-plated box 
of thin, perforated, crucible steel, cut from a léng 
strip of that material, 0.003 inch (0.075 millimeter) 
thick, A cover or lid of the same material is then 
Jaid over it, so that the briquet is closely envel- 
oped by the sides and watls of its perforated steel 
box, The boxes are then placed in the Openings or 
holes in the nickel-plated stect grid, and closely fit 
the same. The assembled plate is then placed in a 
hydraulic press, and subjected to a total pressure 
sof about roo tons, ‘This pressure not only tightly 
closes the boxes, but it also forces their metal sides 
over the adjacent sides of the recesses in the steel 
grid, thus clamping the whole mass into a single 
solid and rigid steel plate, with the hollow “window 
panes” full of active material, The nickel-plating of 
both grids and boxes aids in securing good, perma- 
nent electric connections between them, The finished 
plate has a grid thickness of 0.024 inch (0.61 milli- 
meter) and a “window” or pocket thickness of 0.1 inch: 


(25 millimeters). This is the maximum thickness of ! 
the plate at any point, but, being of steel, the plate : 


has ample rigidity, 

The positive briquets (zines of a primary cell) 
are made by mixing a finely divided compound of 
iron, obtained hy a speciat chemical process, with 
a_nearly equal volume of thin flakes of graphite. 
The graphite does not enter into any of the chemical 
actions, but increases the conductivity of the briquets, 
The graphite is divided into very thin lamina by a 
chemical process, and these are passed through siey 
of screens so as to leave a size ‘or area of flake that 
is much larger than the area of the perforation in the | 
stecl windows, The mixture is then pressed into 
briquets in a mold under a hydraulic pressure of 
about two tons per square inch. ‘The briquets haye 
a surface area of nearly three by % inch on each 
face, The negative briquets (carbon of a primary 
cell) are made by similarly mixing a finely divided 
compound of nickel, obtained by- special chemical 
nicans, with nearly equal bulk of fine flakes of graph- 
ite, and solidifying the mixture in a mold into 
briquets of the same size as above, -A suitable num- 
her of positive and negative plates are assembled 


together, being separated from one another only by 7 


a thin sheet of perforated hard rubber, 


The assembled plates are placed in a vessel, or ex- | 


ternal containing-cell, of sticet steel, containing the 
potash solution, which, of course, does not attack - 
steel, There was, however, much difficulty froin 
the action of the potash on the soldered scams of the 
steel containing-vessel. After many trials, how- 
ever, Mr. Edison found a solder which seems to 
be entirely unaffected by the alkali. In charging, 
the current is, of course, sent into the positive pole 
and its attached negative nickel plate, through the 
electrolyte, and into the positive plate of the iron 
compound which carries the negative pole, 

This current deoxidizes or reduces the compound 
to spongy, mietallic iron and carries the oxygen 
through the ‘film of electrolyte to the nickel com- 
pound, oxidizing it to the hyperoxide of nickel, NiO: 
a higher oxide than the peroxide. In other word. 




















































































































































ae 


























































































































the charging current simply carries oxygen He ed 
opposite direction against the forces of chemical aftin : 
ity, from the iron to the nickel, and stores the ener 
in the ‘reduced iron, which is, of course, unaffected 
aud passive in the presence of the potash solution. 
On discharge, the current passes from the positive 
pole through the external circuit to the negative po! es 
ait its attached iron or positive plate, and then 
throngh the solution to the negative or superoxide 
In go doing, the oxygen moves back ngainst 
the current:and partially reduces the nickel ae 
oxide, NiO; while oxidizing the spongy tron. Hi 
energy of burning of the iron and oxygen, W hich 
t would be developed as heat in the ordinary chemi af 
process, is now liberated in the circtit as elcetrica 
energy. . 

ooh cell is an oxygen-lift. Charging pulls the 
oxygen away from the iron and delivers it tem- 
porarily to the nickel. The condition is then stable, 
until the circuit of the cell is completed, Discharge 
then allows the oxygen to fall back from the nickel 
to the iron with the natural aftinity of iron and 













plate. 



































‘netfon is very different from that which takes 
' place in the lead storage Here, neglecting com 
tions, the action is usually cere for a4 
cal purposes as being represented by the equation, 
PLO, 4 ILSO: -+ Ph = PbSOs + 21,0 -+ PSO, 
+ 100 watt-hours, where the left-hand side repre- 
sents the condition of charge, and the right-hand side 
the condition of discharge. Here oxygen is not sim- 
3 . 7 : ply transferred in discharge from the peroxide to 
the spongy lead, but the solution is changed A(theoret- 
) from an aqueous solution of sulphuric acid to 
plain water. Of course the discharge could not prac- 
tically be carried to the point of denuding the solu- 
tion of all sulphuric acid, and a surplusage of acid 
mitst be used, ‘The equation gives a more theoretic 
- outline of admittedly very complex reactions. In 
at other words, the specific gravity of the sulphuric 
acid solution falls during the discharge, and_ the 

_. solution enters into the chemical combination, The- 

oretically, for every 44s grammes of active material 
' on both "plates, 196 grammes of sulphuric acid are 
reqttired to effect the combination, or 44 per cent, 
by weight of the active elements, and in practice 
it is usual to allow a weight of sulphuric acid nearly 
equal to half the weight of the elements or about 
one-quarter of the total weight of the cell. 

In the new Edison cell, on the other hand, the 
theoretical action of the potash solution is merely 
to provide the proper channel through which the 

5 ions may travel in one direction or the other 
—positive plate to negative plate in’ charge, and 
negative plate to positive plate in discharge, Con- 
sequently, the amount of solution needs only to be 
sufficient to fulfit: mechanical requirements. It is 
helieved that the weight of solution will in practice 
be only about 20 per cent. of the plate weight, or 
about 14 per cent. of the cell weight, In fact, the 
cell may be worked in the same manner as the so- 
called primary (dry) cells. Morcover, if the solu- 
tion should escape, or be carried away by gasing in 
charging, the only detriment seems to he the loss 
of active surface therchy occasioned, and it will only 
be necessary to fill up the cells to the proper level 
with walter from time to time, as evaporation or gas- 
ing may lower the level. For the same reasons the 
specific gravity of the electrolyte does not appre- 
ciably vary during charge and discharge. 

. The briquets of active material slightly expand on 
receiving oxygen, and slightly contract on delivering 
it; that is to say, the iron briquets contract and the 
nickel briquets expand during charge, while on dis- 
charge the iron briquets expand and the nickel 
briquets contract, ‘The expansions and contractions 
of the briquets appear to be well within the elastic 
limits of the spring steel containing-boxes, and con- 
sequently the electric contact is always secure, The’ 
covers or sides of the window pockets. merely ap-| 
proach to, or recede from, cach other slightly during 
charge and discharge, Fortunately, steel is the metal 
which possesses this mechanical elasticity 
marked degree. 

The action of the charging and discharging cur- 
rent upon the briquets seems to be transferred from 
their external surfaces inward in a manner similar 
to the transfer of carbon and oxygen in the process 
of making malleable cast iron in the-furnace, on the 
principle of cementation. No active material has been 
found to be cj led from the briquets through the win- 
dow perfora ious, even under deliberate overcharging 
and discharging. Such gas as is thereby produced 
makes its appearance on the external surface of the 
windows. If the nickel compound had no affinity for 
oxygen, so that energy was neither developed nor

nickel compound be exothermic or energy-releasing, 
then the watt-hours delivered (and the elestromelye 
force) will be lessened by the cnergy iocesstelly 
paid back to break up the combination, If, on the 
other hand, the combination is endothermic or ene 
ergy-absorbing, then the watt-hours delivered (and 
the electromotive force) will be increas edd by the 
energy restored on breaking up the combination, 

Since the superoxide scems not to have, been 
known hitherto, no information concerning its en- 
ergy of combination is obtainable, ‘The clectromo- 
tive force of the cell seems to be so near to that of 
the union of iron and oxygen as to suggest that the 
nickel ‘superoxide is not far from being neutral, or 
that the nickel compound has but litte affinity for 
oxygen, although the superoxide appears to be quite 
stable in the cell. ; : 

The new cell dacs not scem to be appreciably in- 
fluenced by changes of temperature, and should stand 
a very low temperature without detriment. The elec- 
trolyte—potash—does not attack any of the ingredi- 
ents of cell, nor are any of the ingredients soluble 
therein, No local action occurs in the ecll so far as 
has yet been observed, since the electromotive foree is 
below that necessary to decompose water, ‘I he cell 
may be fully discharged to the practical zero point of 
electromotive force without detriment. In fact, a 
cell has not only been completely discharged, Dut ree 
charged in the reverse, or wrong, direction, and after 
bringing it back to its originally charged state hy 
proper restoration of direction of charging current, 
the storage capacity remained unaffected, It would 
seem, therefore, that the cell should be capable of 
withstanding mutch abuse. : 

Mr. Edison states that “the negative plate (nickel) 
either charged or discharged, can be removed from 
a working cell, and dried in the air for a week; with- 
out appreciably injuring it, and when the plate is 
finally replaced in the cell its charge is practically 





an_ clectromotiv: 















undiminished.” The positive (iron) plate, if sim- i : 
ilarly removed from the cel! would be likewise unin- 


jured, but it soon loses its charge hy the oxidation 
of spongy iron with accompanying liberation of heat 
and appreciable rise of temperature extending over 
a period of several hours. On replacing -the elec. 
trode, however, in the cell, the storage capacity is 
unaffected on recharge. “ 

As regards cost, Mr. Edison believes that after 
factory facilities, now in course of preparation, have 


been completed, he will be able to furnish the cells |) 


at a price per kilowatt-hour no greater than the pre- 
vailing price of lead cells. 

Having now considered the action and properties 
of the cell, a brief description may be given of the 
difficulties encountered in developing it. 


The phenomenon of passivity has probably kept |, 


inventors from finding this cell in the past, Mr. 
Edison believes that of all the very numerous com- 
pounds of iron, and of which he has tried many 
hundreds, the particular compound which he pre- 
pares is perhaps the only one capable of being used. 


If the dried hydrates or oxides of iron, native or ; 


artificial, are subject to electrolytic reducing action 
in any alkaline solution, they remain inert and un; 
affected, On the other hand, if finely divided iron 
obtained by reducing a compound of iron under 
the action of a reducing agent, stich as hydrogen or 
carbonic monoxide, is subjected to electrolytic oxida-, 
tion in an alkaline solution, it is inert and cannot 
be oxidized. 
State. The same difficulty of passivity affects the 
use of nickel or the negative element. Finely di- 
vided nickel, reduced from a nickel compound, re- 
mains inactive when subjected to electrolytic oxygen 
in an alkaline solution. The monoxide and the black 
oxide or peroxide are also inert. No oxide of nickel 
is active or can be made active by electrolytic action, 
peroxide does not act as a depolarizer.

Mr. Edisén has given the world what 
_ promises to be another epoch-making in- 

vention. ; ae 
‘This remarkable man has signalized his 
return to the field of electrical invention 
{by ‘the announcement of the long-sought 
and ‘urgently needed light storage bat- 
tery, and has accomplished his result after 
the manner that marks all really great 
inventions—through means of tho great-

will be found an account of the method—

that for the same weight the.new storage

‘cal Engineers, and reproduced in this issue. So many inaccurate 
| notions have been formed of late concerning this cell, partly owing 
‘to a certain German patent recently granted to Mr. Edison for a 


cadmiwum storage cell, that it is gratifying to receive a clear and prac- 
‘tical authorized statement of the facts, 





| ‘The great advantage of the new cell is that it is structurally com- 
posed of steel instead of the eternal Jead of the past, a relatively weak 
‘and heavy metal, Mr, Edison is said to have observed some years 
i ago that if the Creator had intended that lead should be used in a 
storage cell, he would not have given to that metal its high specific 
° gravity, With steet plates the structure of the cell can be designed 
i for strength and rigidity with the minimum mass of inactive material, 
Another advantage of the cell is its absence of “formation,” or the 
‘period of incubation through which the leaden cell has to pass in 
‘order to develop its storage capacity. We understand that when the 
: chemical salts are inserted in the receptacles of the plates, they are 
{ready for charging in the ordinary way, which is an obvious advan-

but their lives under active work would be short and have not tha 
merit of being even merry. The fact that the alkaline solution of the

; unaltered during charge and discharge, is another advantage, Part of 
' the fall ine. m, f£ of the lead cell during discharge must be attributed 
‘ to local chemical exhaustion of the acid solution in the pores of the

The New Edison Storage Battery.* 


By Dr. Artiur E, Kennety, : 


T is welt known that the history of the storagecell is essentially 
that of the lead cell discovered by Plante in 1860, in which lead 
peroxide is the depolarizing substance, An enormous amount of 

labor has, in the aggregate, been expended upon the improvement of 
this cell in the hands of experimentalists, As a result of that labor, 
the storage battery has at last become a recognized adjunct to direct- 
current central stations, but it has limitations that seem to withstand 
further attempts toward improvement, Of recent years, hardly any 
success has been met with in the direction of reducing its weight for 
a given energy-storage capacity, without detriment to endurance, and 
this weight is the great drawback of the storage battery in electric 
storage traction, and has been the principal obstacle to its advance in 
this direction for the past 20 years, 1 

In practice, the storage energy per unit mass of ithe modern lead 
battery, is from 4 to 6 watt-hours per pound of battery (8.8 to 13.23 
watt-hours per kilogramme. Expressed in another way, a battery 
weighs from 124.5 to 186.5 Ibs. per horse-power-hour at its terminals 
(75.5 to 113.4 kilos per kilowatt-hour) ; of, if its stored energy avail-

able at terminals were all expended in gravitationat work, a battery 
could raise its own weight through a vertical distance of from two 
to three miles (3.2 to 4.8 kilometers). ; 

While it is possible to increase the energy per unit mass by making 
the electrodes very light, yet this is always found to be followed by 
a very heavy deterioration. - 7 7 

Many attempts have also been made to perfect storage cells of the 
alkaline-zincate type, but the great difficulty of depositing zine in co- 
herent form from the solution, as well as the lack of a depolarizer 
that shall be insoluble in the electrolyte, has stood in the way of this 
cell’s success. ‘ 

Mr. Edison set himself the task of finding a cell which should pos- 
sess the following advantages: 

1. Absence of deterioration by work. 

2. Large storage capacity per unit of mass. : :

| charge, the current passes from the positive pole through the ex- 
<i ternal circuit to the negative pole, and its attached iron or positive 
5 plate, and then through the solution to the negative or superoxide 
“ plate. In so doing the oxygen moves back against the current and 
partially reduces the nickel superoxide Ni 0; while oxidizing a

The cell is an oxygen-lift, Charging-pulls the oxygen away from 
‘the iron and delivers it temporarily to the nickel. ‘The condition is 
‘then stable, until the circuit of the cell is completed, Discharge then 
‘allows the oxygen to fall back from the nickel to the iron with the 
‘natural affinity of iron and oxygen. . ; 
This action is very different from that which takes place in the lead 
' storage cell. Here, neglecting complications, the action is usually Tee 
garded for practical purposes as being represented by the equation 


PLO: + 2H:SO 1+ Pb os 2Pb SOv+2H0 -+- 100 watt-hours, 


where the left-hand side represents the condition of charge and the 
ight-hand side the condition of discharge. Here oxygen is not sim- 
; : ‘ply transferred in discharge from the peroxide to the spongy lead, but 
a : the solution is changed (theoretically) from an aqucous solution of 

“sulphuric acid to plain water. Of course, the discharge could not 

‘practically be carried to the point of denuding the solution of all 

sulphuric acid, and a surplusage of acid must be used, The equation 

gives a mere theoretical outline of admittedly very complex reactions. 

In other words, the specific gravity of the sulphuric acid solution falls 

during the discharge, and the solution enters into the chemical com- 

bination. Theoretically, for every 445 grammes of active material 

on both plates, 196 grammes of sulphuric acid are required to effect 

: the combination, or 44 per cent by weight of the active elements, and 

in practice it is usual to allow a weight of sulphuric acid nearly equal 

‘to half the weight of the elements, or about one-quarter of the total 
- weight of the cell. 

In the new Edison cell, on the other hand, the theoretical action of 
the potash solution is merely to provide the proper channel through 
which the oxygen ions may travel in one direction or the other— 
positive plate to negative plate in charge, and negative plate to posi- 
tive plate in discharge, Consequently, the amount of solution needs 
only to be sufficient tovfulfill mechanical requirements, It is believed 
that the weight of solution will in practice be only about 20 per cent 

of the plate weight or about 14 per cent of the cell weight. In fact, 
the cell may be worked in the same manner as the so-called primary 
“dry-cells.” Morcover, if the solution should escape, or be carried 
away, by gasing in charging, the only detriment seems tobe the loss 
of active surface thereby occasioned, and it will only be necessary to 
fill up the cells to the proper level with water from time to time, as 
evaporation or gasing may lower the level, .For the same reasons the 
specific gravity of the electrolyte does not appreciably vary during 
charge and discharge. 
The briquettes of active material slightly expand on receiving 
oxygen, and slightly contract on delivering it, that is to say, the iron 
: briquettes contract and the nickel briquettes expand during charge, 
rae . While on discharge the iron briquettes expand and the nickel briquettes 
*. contract. The level of the solution is in this way scarcely affected. The 
, expansions and contractions of the briquettes appear to be well within 
» the clastic limits of the spring-stecl containing boxes, and conse- 
quently the electric contact is always secure. The covers or sides of 
the window pockets merely approach to or recede from each other 
slightly during charge and discharge. Fortunately, steel is the metal 
which possesses this mechanical elasticity in a marked degree, 

The action of the charging and discharging current upon the 
briquettes seems to be transferred from their external surfaces in- 
wards in a manner similar to the transfer of carbon and oxygen in 

‘the process of making malleable cast-iron in the furnace on the prin- 

i ae of cementation, No active material has been found to be ejected 

} from the briquettes through the window perforations, even under the 
j deliberate overcharging and discharging, Such'gas as is thereby

If, on the other hand, the combination is endothermic or cnergy- 
absorbing, then the watt-hours delivered (and the e, m. £.) will be}: | 
increased by the energy restored on breaking up the combination, 
Since the superoxide seems not to have been known hitherto, no in- 
formation concerning its energy of combination is obtainable. The ‘ 
ce. m. f. of the cell seems to be so near to that of the union of iron 
and oxygen as to suggest that the nickel superoxide is not far from 
being neutral, or that the nickel compound has but Tittle affinity for 
oxygen, although the superoxide appears to be quite stable in the 
cell. : 

The new cell docs not seem to be appreciably influenced by changes 
of temperature, and should stand a very low temperature without 
detriment. The electrolyte—potash—does not attack any of the in- 
gredients of the cell, nor-are any of the ingredients soluble therein. 
No local action occurs in the cell so far as has yet been observed 
since the e. m. f. is below that necessary to decompose water, 

The cell may be fully discharged to the practical zero point of 
e. m. f, without detriment. In fact, a cell has not only been com- 
pletely discharged, but recharged in the reverse or wrong direction, |’ 
and after bringing it back to its originally charged state by proper 
restoration of the direction of charging current, the storage capacity |° 
remained unaffected, It would seem, therefore, that the cell should 
be capable of withstanding much abuse. 2% 

Diagrams are shown on screen giving the curves of discharge of 
experimental cells, 

Mr. Edison states that “the negative plate (nickel) either charged 
or discharged, can be removed from a working cell, and dried in the 
air for a week, without appreciably injuring it, and when the plate |. 
is finally replaced in the cell its charge is practically undiminished. 

The positive (iron) plate, if similarly removed from the cell wilt 
be likewise uninjured, but it soon loses its charge by the oxidation 
of the spongy iron with accompanying liberation of heat and appre- 
ciable rise of temperature extending over a period of several hours, 
On replacing the electrode, however, in the cell the storage capacity 
is unaffected on recharge. é 

As regards cost, Mr. Edison believes that after factory facilities 
now in course of preparation have been completed, he willbe able 
to furnish the cells at a price per kilowatt-hour not greater than the 
Prevailing-price of-lead cells, * 

Having now considered the action and properties of the cell, a 
brief description may be giyen of the difficulties encountered in 
developing it. ey : 

The phenomenon of passivity has probably kept inventors from 
finding this cell in the past. Mr, Edison believes that of all the very 
numerous compounds of iron, and of which he has tried many hun- 
dreds, the particular compound which he prepares, is perhaps ths 
only one capable of being used in this way. : 

Tf the dried hydrates, or oxides of iron native or artificial, are 
subjected to electrolytic reducing action in any alkaline solution, 
they remain inert and unaffected. 

On the other hand, if finely divided iron obtained by reducing a 
compound of iron under the action of a reducing agent, such as 
hydrogen, or carbon monoxide is subjected to electrolytic oxida- | ‘ 
tion in an alkaline solution it is inert and cannot be oxidized, It 
assumes the well-known passive state, 5 

The same difficulty of passivity affects the use of nickel or the 
negative element, Finely divided nickel, reduced from a nickel com- 
pound, remains inactive when subjected to electrolytic oxygen in an 
alkaline solution, The monoxide and the black-oxide or peroxide 
are also inert, No oxide of nickel is active or can be made active |. 
by electrolytic action, and the peroxide docs not act as a depolarizer.

—"Oir Fheoretical Concentration Changes in the New 
Edison Battery. 





By E. F, Roeper, Pit.D, 
N this article I intend to draw some conclusions from the mod- 
I ern theory of the electrolysis of aqueous solutions regarding 
1 the working of the new Edison battery, As I have had no op- 


able either to confirm or to refute my results, It seems to me, how- 
ever, quite legitimate and interesting to discuss the processes in the 
new Edison cell from the point of view of a theory which, in the 
opinion of many, gives a good description and explanation of a large 
number of electro-chemical facts. / . 

The following research refers not only to the Edison nickel-iron 
cell, but to the general type of cell of which the new Edison cell is 
a special example, This general type may be characterized as a cell 
in which the chemical process during charge and discharge consists 
in the transport of oxygen from one plate to the other, while the 
chemical composition and the total concentration of the electrolyte 
(i, ¢, the ratio of the total number of molectiles of the dissolved 
electrolyte to the total number of water molecules) remain un- 
changed. 

I have defined the “total concentration” of the electrolyte in this 
exact way, to avoid a misunderstanding. This misunderstanding 
would be to assume that the electrolyte is not changed at all, From 
all electro-chemical facts, however, we know that an electrolyte al- 
ways undergoes concentration changes during electrolysis. If the 
“total concentration,” as defined above, does not change, there are 
nevertheless concentration changes in the different parts of the elec- 
trolyte; either the concentration of the solution increases at the 
anode and decreases at the cathode, or it decreases at the anode and 
increases at the cathode. It will be shown presently that Hittorf's 
theory leads to such conclusions for the Edison battery, and the nu- 
merical data will be given. These changes of concentration, how- 
ever, must have some influence upon the practical working of the 
Edison cell. This may be concluded from the analogy with the lead 
accumulator, where the concentration changes in the porous plates 
are of the greatest importance for the behavior of the battery. 

It may be of advantage to give a brief review of a few characteris- 
tic examples of the general type of the Edison cell. 

Silver-Copper Battery.—This somewhat expensive, but theoreti- 
cally very interesting battery has been devised by Mr, E, W. Jungner 
(German Patent 110,210, March 31, 1899; see also Centralblatt f, 
Accum, 1%, Elementenkunde, April 15, 1900, and’ Elektrochemische 
Zeitschrift, August, 1900). The positive plate is peroxyde of silver 
in a finely divided state, the negative plate copper ina finely divided 
State, the electrolyte is an aqueous solution of potassium hydroxyde, 
The discharge consists of two steps, the chemical reactions during 
these two steps being represented respectively by the equations 


Ay: Osa Cu= Age O+CitsO 








and 


Ags O + 2Cu= Ags + Cus 0 


The ec, m. f, of the first step corresponds to the difference between 
the formation heats of dg: O: (from Ags O and O) and Cis O (from 
2Cuand 0). Thee. m. f. of the second step corresponds to the dif- 


and Cu: O (from 2 Cu and 0), 
Copper-Cadmium Cell.—This is an older cell of Mr. Edison, which 
was described in the ELecrricat Wortp AND Enatnerr, April 6, 1901, 
Nickel-lron Cell—This is the new cell of Mr. Edison, described 


Ennerr, May 23, 1901). The positive plate is a “compound of 
nickel” in a finely divided state, the negative plate is a “compound 
+ of iron” in a finely divided state, the electrolyte is an aqueous solu- 
{ tion of potassium hydroxide. If the “compound of iron” at the be- 
t ginning of the discharge is expressed by Fe and the “compound of 
q nickel” by NiOm-where Fe and NiO: may not represent the exact 
i chemical composition, but are simply convenient signs—the chemical 
| action during discharge is given by the formula 


NiOs-+ Fe =NiO-+ FeO (1) 
It will be seen that in all examples of this type of battery during 
the discharge the positive plate is reduced from a higher state of 


oxidation to a lower state of oxidation, and the negative plate is 
4 oxidized from a lower state of oxidation to a higher state of oxida-

tion, while the chemical composition of the electrolyte is not changed.’ 
The electrolyte in all these batteries is an aqueous solution of potas- 
sium hydroxide, or of sodium hydroxide, or, gencrally speaking, of 
“any metallic hydrate ae in bi and having a metallic radicle 
vhi ecomposes water” (Jungner). , 
ie Ceacalod which followed Dr. Kennelly’s paper, Mr. CJ. 

Reed has pointed out the following features which make this gen- 
eral type of battery extremely interesting. The capacity of the cell 
is not limited by the quantity of the electrolyte. Very little electro- 
lyte is therefore required in it, the electrodes can be brought near 
together, and the resistance and the weight are thereby diminished, 
Further, the resistance of this type of cell will tend to remain con- 
stant to a far greater degree than that of the lead accumulator, In 
the latter lead sulphate is formed during discharge, which is a far 
poorer conductor than the oxides in the Edison cell. Finally, Mr. 
Reed pointed out that with this type of cell there is a possibility to 
charge it by a non-electric method, i, e., to reduce the one plate and 
oxidize the other plate outside of the jar by a non-electric method, 





















































transforming heat and chemical energ} from other sources into 
electrical energy—an instrument for an indirect process of get- 
ting electrical energy, possibly out of carbon, and perhaps a very 
economical process. 

Now, the question arises: What is the action of the electrolyte 
during charge and discharge? What is the mechanism by which the 
electrolyte transports oxygen from one plate to the other plate? To 
discuss this question, I will assume as fundamental hypothesis the 
so-called “theory of electrolytic dissociation.” According to this 
theory, there is in an aqueous solution of KOH a certain number 





















































gram ion K being charged with 96,540 coulombs of positive clec- 
tricity and each univalent gram ion O H being charged with 96,540 
coulombs of negative electricity; 1 gram ion means so many grams 
as the equivalent weight indicates, The degree of ionization (i, ¢, 
the ratio of the number of molecules K OH, split up into ions, to 
the total number of molecules K OH, dissolved in the water), de- 
pends upon the concentration and may be determined by Arrhenius’ 
method by a measurement of the electric conductivity. Only the 
charged ions K and OH are active in the conduction of electricity 
through the electrolyte. The water molecules and the neutral K OH 
molecules which are not split up into ions, are inactive. When 96,- 
§40 ampere-scconds flow through the electrolyte, 1 positive gram ion 
is set free at the cathode and gives off its charge and 1 negative gram 
idris set free at the anode and gives off its charge so that indeed 
96,540 coulombs of positive electricity have been transported from 
the anode to the cathode; or when 1 ampere-second flows through the 





































electrolyte, =0.0000104 positive gram ions and o.ooco104 neg- 





ot 
96,540 
ative gram ions are set free. This is nothing else than Faraday's 
law, which states that o.cooo104 gram equivalents K OH are decom- 
posed by 1 ampere-second. 

Tf we apply this scheme*to the new Edison battery we find that 
when in discharging it gives off 296,540 ampere-seconds, two 
gram fons O H become free at the Fe plate and two gram ions K 
at the NiO; plate, The chemical reactions at each plate may then 
be represented by the following formulas: 


Fe+20H=FeO+H,0 














(2) 
Ni0:+2K+Hi:O=Ni0+2KOH (3) 


The summation of these two formulas gives, of course, again equa- 
tion (1), but these two formulas show more than equation (1). It 
will be seen from (2) and (3) that in the dischrage of 2X 96,540 
ampere-seconds the chemical reactions at the electrodes cause the 
formation of one molecule of water at the Fe plate, and the con- 
sumption of one molecule of water at the Ni Os plate, so that the 
solution at the Fe plate thereby becomes less concentrated, and that 
at the NiO; plate more concentrated, A 

For the chemical reactions (2) and (3) we assumed that 2 ions 
O H and 2 ions K are svt free at the iron and nickel plate, respec- 
tively. How did they come there? The theory assumes that they 
have come there by migration, that ail positive K ions have migrated 
with a certain speed in the direction of the current, and all O H ions 
with a certain speed in the opposite direction. The question of the 
relative speeds of the two kinds of ions was first discussed by 
Hittorf. Let us assume we have at the beginning of the electrolysis 
m ions K and m ions O H in the solution. To get a convenient me-

it might be supposed that the mieasurements of specific gravity have 
been made in the liquid in the middle Part of the cell between the 
two plates, . 

From the point of view of our theory there appear to be reasons 
why the diffusion shotld act more quickly in the Edison battery than 
in the lead accumulator, The diffusion is the greater, the greater the 
differences of concentration and the nearer the places of different con- 
centration, In the lead accumulator the solution in the middle part 
of the cell, while not altered by the immediate action of the current, 
diffuses to both sides, as at both sides the concentration has de- 
creased, In the Edison cell there is practically no middle part of the 
cell, and the places of the concentration differences in the pores of the 
two plates are very near together, so that diffusion brings the solution 
from the pores of the nickel plate, where the concentration increases 
to the pores of the iron plate, where the concentration decreases, 

There is another, apparently very important point. We know that 
the form of the charge and discharge curves of the lead storage bat- 
tery, and the whole question of the “reversibility” of its action, are 
intimately connected with the concentration changes in the pores of 
the two plates (sec the book quoted above by Dr, Dolezalel, Chapters 
VUI, and IX.). The question naturally arises: Are the concentra- 
tion changes which must occur in the Edison battery according to 
the theory given in this article of an analogous importance for the 
working of the Edison cell? But it scems to me premature to at- 
tempt an answer to this question as long as experimental data are 
lacking regarding the influence of the concentration of the solution 
upon the em. f. of the cell and especially upon the em. f.’s at both 
terminals separately. 


By E. C, Rozerrs, 


HE interest excited by the demonstration before the American 
T Institute of Electrical Engineers, at its recent Conversazione, 
of the mercury lamp of Mr. Peter Cooper Hewitt, has made 
it seem worth while to call attention to another research carried out 
along similar lines by L. Arons, in Berlin, In Wiedemann’s Annalen' 
he published a description of what 
he called a mereury are light (das 
Quicksilber Lichtbogen). He 
says of it, “While studying gas- 
vous conduction I discovered an 
extraordinarily good arrangement 
for maintaining an are between 
mercury electrodes for long peri- 
ods and without any of the usual 
troubles incident to such cases.” 
The apparatus usually took the 
form shown in the drawing. Here 
the short leg of an L-shaped 
tube is sealed off, and provided 
with an electrode. The other end 
of the tube is. open, and is con- 
nected to a mercury reservoir by a 
rubber tube. The tube is exhausted 
to a vacuum corresponding to a 
pressure of 1 or 2 mm. of mercury. 
When in use the electrodes are 
connected through a controlling 
resistance to a, source capable of 
maintaining a difference of poten- 
tial of about 100 volts. In starting the are, the mercury is raised in 
the tube by means of the reservoir till it flows over into the short leg. 
It is then immediately lowered. As soon as the mercury breaks at 
the top, a brilliant discharge passes from one electrode to the other. 
Its color is a greenish white, In two later papers* he gives‘the fol- 
lowing results: , 

1, At currents between § and 9 amperes the voltage drop is prin- 
cipally dependent on the length of the tube. Experiment showed that 
the drop per cm. was approximately .6 volt for a current of 6.5 am- 
peres, The electrode loss is 8 volts at the anode and 6 volts at the 
cathode. 

2. The specific conductivity of the vapor is 6x 10, which is &

times as great as that

3. The temperature of the discharge was great enough to melt thin 
platinum wire at the center of the tube, The average temperature 
was 470 degs. C. above that of the room, while computation based 
on Warburg's experiments’ showed that at the center, with a cur-

Storage Battery Patents, 





Among the patents of June 4 are three issued to W. J. Buckley 
on novel forms of storage batteries, One of these is a high-ten- 
sion battery—that is, one in which the e m. f. of each pair of 
plates is added to that of its neighbor, a number of pairs being con- 
tained in a receptacle commen to all the clements, The receptacle is 
divided into compartments by liquid-tight metallic partitions; on 
one side of a partition and in metallic connection therewith is a 
positive plate and on the other side a negative plate. These plates 
do not quite extend to the bottom of the teceptacle, so that the 
electrolyte in’ a single compartment is in communication with the 
two partitions of that compartment and the two sides of both plates 
therein, Another patent describes a battery formed of a number of 
similar plates, separated by a continuous metal band around the 
edges of cach pajr. Any flat plate or grid may be used having a solid 
metal core or otherwise made liquid tight, should the various ele- 
ments be included in a serial circuit, When, however, the battery 

$s are intended to be placed in a cell having an electrolyte com- 

"to all the plates, as when in parallel circuit, then the liquid- 
_ quality of the plates is not essential. In the space formed be- 
tween plates by the separating metal band is placed powdered or gran- 
war carbon, such as wood charcoal. The inventor states he has found 
that the charcoal used as a separator has the quality of absorbing 
Gases to a high degree. The gas is readily absorbed as fast as 
evolved, and while the charcoal is to some extent an electrical con- 
ductor, and while it is also true that there is a natural electrical po- 
tential difference between the carbon and the metallic electrodes, 
which difference may produce a slight local action in the cell, yet he 
States that the benefit derived from the tse of charcoal over-balances 
this objection, . 

A third Buckley patent describes a battery formed of super- 
posed trays separated by -an insulating materint in the form of a 
grid. Small notches are cut in the tops of the grid cross bars to 
ive passage to the electrolyte, The grid compartments are filled 
with coke and oxide of lead. A number of such tray elements are 
nested to form a cell. The lower tray rests in a wood support the 
shape of the bottom of the tray, and a similar one, but convex, fits 
into the upper tray, the two being bolted together. A patent issued 
on the same date to G. W. Hough, describes a battery consisting of 
plates of semi-circular form, with pockets formed by cross ribs for the 
active material, which is filled’in flush with the tops of the ribs. 
The plates are sct up in a horizontal position, the negatives 
forming one half-cylindrical pile, and the positives another similar 
pile, the whole forming approximately a cylinder, with the two piles 
electrically separated, Conducting lugs are cast to the edges of each 
pile, 

A patent issued on the same date to C. L. R. E, Menges, The 
Hague, Holland, describes a+ storage battery of cellular con- 
struction, in cach compartment of which are plates of only one 
polarity. In its simplest form, the receptacle consists of a number 
of chambers separated by non-conducting permeable partitions, In 
one chamber there are two positives, one in contact with each parti- 
tion, and in cach of the adjacent chamber two negatives in con- 
tact with the respective partitions, and so on. Ina practical cell the 
non-condticting permeable partitions may consist of a supporting 


‘piece of insulating material with perforations and channels: covered 


by a porous non-conducting substance, and ‘with active material on 
both sides. In a patent issued June 11 to V. G. Apple a “two-cell 
integral unit” battery is described. A lead or alloy case or box is 
divided in the center by a partition of similar material, thus forming 
two compartments. The interior surfaces of each compartment is 
provided with indentations for containing active material, space for 
‘the electrolyte being left after the active material is applied. Each 
of such cells we give four volts, A patent granted June 18 to Wilson 
H, Abbey and Jacob Altmos describes an element formed of a corru-

the alkali to form a potassium salt, which diffuses out of the mass, 
land the iron being converted to an hydroxide thereof. The diffusion 
jof the alkaline sulphur compound is facilitated by alternately re- 
versing the oxidizing current to subject the contents of the plate to 
successive oxidation and reduction until the whole of the sulphur 


‘fis eliminated. The element will then be ready for use when the

iron capable of reduction Appears to be that produced as explained ing the make-up of the oxidizable clement. These plates are then 


immersed in a solution of potassic hydroxide in water, and sub- 
jected for a considerable time to an oxidizing current of about 8 
milliamperes per square centimeter of surface, thereby converting 
the first oxide to a higher oxide, whereupon the clement is ready for 
use. The object of employing graphite is to offer a great extent 
of surface against which nearly the whole of the oxide is in contact, 
this being necessary since the electrolytic reduction and oxidation 
do not extend toa great distance from the conducting surface against 
which the oxide is in contact, although the higher oxides of nickel 
and cobalt seem to be conductors, Graphite is neither affected by 


electrolytic oxidization, nor is there local action between it and the ; 


oxides, Nickel hydrates instead of other nickel compounds are pref- 
erably used because they are casily prepared, and by absorption of the 
liquid they swell within the pockets to insure intimate contact and 
stability, while they are not reduced to the metallic state elec- 
trolytically. 

The elements are preferably utilized together in a solution of 25 
per cent of potassic hydroxide in water. Owing to obscure reac 
tions when the battery is discharged, and to a change of resistance 
in the electrodes, the voltage of the improved cell is invariable, but 
averages 1 volt, rising as high as 1.38 volts when freshly charged. 
The battery can be over-charged, fully discharged, or even reversed 
and charged in the opposite direction without injury. Over-gassing 
does not disturb the initial state of the clements, All the ingre-

A German translation of this patent is also contained in the Cen- 
tralblatt fucr Accumulatoren und Elementen-Kunde, June 15, to 
which the editor of that journal adds the following critical note: 

“The patent in its essential parts combines only known elements. 
Higher nickel oxydes have been used by Michalowski for the posi- 
tive plates, and iron was long ago proposed for the negative plates, 
Only the constructive details and the formation are new.”

April 19, 1899) patents the use of peroxide of nickel NixOs as posi-

the nickel plates as follows: He heats a metallic nickel plate in pure 
oxygen or in gases containing oxygen, to a temperature above 300

It is this simplicity of ultimate action which makes the Edison 
storage cell a special type of voltaic apparatus, and which also sup- 
ports the hope of our reaching a chemically regencrative cell of this 
type, the transfer of oxygen in charging being then effected by some, 
purely thermo-chemical process. The efficiency, of this imaginary 
process of furnace charging would not be subject to the thermo- 
dynamic temperature limitations of heat engines, could probably be 
brought to a relatively high value, and might enable electrical energy 
to be obtained from coal. As regards the changes in the cm. f. 
‘which make their appearance in the Edison cell at a certain stage of 
discharge, it seems likely that such change is associated with a 
change in the chemical conditions of the active materials, rather than

by the Accumulatorenwerke System Pollak, according to a German 
patent of Aug, 17, 1898. Iron powder or compounds of oxygen with 
iron are compressed while wet, and are then heated, so that they 
come into a porous but solid state, The electrodes are then formed 
electrolytically, in an alkaline solution, for instance, NaOH. The 
iron powder or the oxygen compounds of iron are generally mois- 
tened with nitric acid or another oxidizing agent, and are afterward 
compressed. The oxydizing agent is then removed by heating to a 
ted heat, or in any other manner, As electrolyte with electrodes of 
this kind, such solutions’ can be used which cither form insoluble 
compounds or none at all, with the electrodes as, for instance, alka- 
lines, bichromate of Potassium, phosphoric acid, ete, 

From these patents it is evident that the “passive state” had not 
kept inventors from using nickel oxyde and iron plates in batteries, 
as had been claimed, On the other hand, the cell, described above, 
of Michalowski, is not of the type of the new Edison battery. 
Michalowski uses zinc as negative electrode, and zinc dissolves, 
The Michalowski cell is therefore of the type of the old Edison-Le- 
dJande cell, Furthermore, Michalowski speaks of Ni.Os plates, while 
Dr. Kennelly, in his Paper on the new Edison cell, expressly states 
that the charged nickel plate in the Edison cell is nickel hyperoxide

Interuban Trolleys in Indiana, 


pea Ds ‘ 

There are now 200 miles of interurban electric road out of Indi- 
‘anapolis, connecting with the principal cities of the Indiana gas belt, 
and there are in round numbers 1000 miles Projected at present for 
Indiana, The interurban roads afford an hour schedule for pas- 
Sengers, and less frequent freight hauls into the city, and are heavily 
patronized by the farmers along the line and the residents of the 
towns and cities which they connect. That they are successful in 
their efforts to get business is evidenced in the efforts of the rail- 
‘roads, whose tracks are now paralleled by the electric lines, Where 
there are parallel lines the railway companies have cut the local 
rates and have put a better train service into operation. Some ob- 
Servers believe that the solution of the difficulty can only be by the 
‘death or absorption of the interurban lines, or the abandonment by 
the railways of their local business. At present there scems to be 
hardly enough business for both. There are those who hold that 
the railroads will absorb the electric lines, but there is no tendency 
‘observable in the present situation that will justify such a conten- 
tion. Both sides are Preparing to fight, and of the contest, in its 
initial stages, no accurate forecast of the outcome can be made, 

A likely development is a combination of the major part of the in- 
terurban lines in the hands of a single syndicate, The Elkins-Widener 
People have lately acquired the Union Traction Company’s tines, 
‘which are the most extensive in the central part of the State. They 
also contro! the Indianapolis Street Railway Company and the Cin- 
‘cinnati street lines. Out of Cincinnati they control a line going 


north into Indiana, Lately they are reported to have acquired the ° 


Indianapolis and Greenfield line. There is at present a line pro- 
jected from Greenfield to Dayton, Ohio, which will complete the 
chain from Indianapolis to Dayton, and lines which will ultimately 
connect Chicago and Cincinnati by way of Indianapolis are talked of, 
It is believed that before many years the Union Traction Company 
will absorb most ef these traction companies, and that there will be 
2 unified system connecting Indiana, Ohio, and Iilinois, 

The last Indiana Legislature made it possible for this outburst of 
traction building to occur by giving the traction companies the same 
tight of eminent domain, allowing them to condemn land, as the 
Tailroads. In this way companies which have been unable to get 
tights of way over the highways are now getting private rights of 
way. The road between Indianapolis and Logansport, which has 
been retarded for two years for this reason, is one that shows the 
utility of the last Legislature. The Indianapolis News publishes a 
map showing the present and projected trolley lines in the vicinity 
of that city. They are so numerous as to present the appearance 
of a spider’s web, with Indianapolis as the central point. The News 
says: “That the railroads feel that they are to be confronted by a 
powerful rival is apparent from the effort the Big Four, the I, & V., 
and the J. &-M. & I. companies are already making to meet compe- 
tition. It is believed by many that the railroads will eventually be 
forced into buying up the electric lines in order to save themselves, 
as it is not thought they can continue the competition for long when 
the odds in operating expenses are so heavily against them. It is

Wisconsin Independent Tetephone Meeting. 





At La Crosse, Wis. last week the Wisconsin independent tele- 
phone companies had a meeting, there being delegates present from 
26 companies in the State. The meeting was held in the city, council 
chamber, when Mayor Boschert welcomed President Hutchinson 
and his associates, and the president made an interesting address, 
Mr. R. S. Abbott read a paper on telephone conditions in Michi- 
gan and Wisconsin, During the afternoon a visit was paid to the 
new La Crosse telephone exchange. 

At the second day’s session a hot disctission relative to the rela- 
tions with the Bell company occurred, The matter came up on a mo- 
tion to exclude all members who are in any way affiliated with the , 
Bell people. The discussion showed a unanimity of determination 
to fight to the bitter end, A resolution was passed that all com- 
panies having any business relations with the Bell company be disci-

A resolution to establish uniform toll charges all over the State 
was passed unanimously. A committee was appointed to take charge 
of the matter, and it is thought probable that a big reduction of toll

primary radiation, the rest being second- 
ary effects, as the cathode Tays generate 
the X-rays and these in turn gencrate 
their complex secondary radiations, 

‘The chemical nature of the radio-active

stood, nor is it surprising when one con- 
siders the difliculty of working with sub-

radium, is definitely established. Hof- 
mann and Strauss thought they had 
isolated another new radio-active element, 
but while still claiming the new element, 
they now admit that it is not radio-active, 

The question of the source of energy in 
these radintiong is yet unanswered. Is 
the energy potential in an unstable molee-

the first case, how long will the energy

For some time Mr. Edison has been 
working to improve galvanic or storage 
* batteries, with a view to increasing the 
permaneney of the same while dcereasing 
the weight. 'T'o this end he devised a cell 
wherein the mnetals, cadmium and copper, 
are employed as the elements in an alka- 
line electrolyte, whereby a Very permanent 
cell was secured, having the initial and 
final states of the electrolyte the same. 
Furthermore, it was capable of storing a | 
greater amountof energy per pound per cell 
thanbatteries commercially nsed before that 
timo for the same degree of durability.

of an clement for furnishing the oxygen 
to the oxidizable element on discharge with 
even greater freedom than oxide of mer- 
cury. At the same time, the new clement 
is leas expensive, is of Joss weight, but

‘ fduced opportunity for the solution to 
Ypenetrate the mass and lowering, in con- 
| f'sequence, its current-condueting capacity. 
“iMctallic iron, even, when finely divided,

i ino of itself oxidize in solutions of the fixed

‘Ja gmall quantity of a soluble ferrate of the

‘Lithe other hand, finely divided iron ob-

ritrolytie oxidation does not form a solu- 
ble ferrate, but is converted into the in- 
soluble ferrous oxide. My improved oxidiz- 
able clement is, therefore, absolutely per- 
Ke manent, go that in the operation of the 
y4 battery the electrolyte is not changed at 
E any stage of the working, and absolutely 
hi no deterioration of the iron clement takes 
| place. Having described the advantages 
ij and characteristics of and the preferred 
4 manner of making the oxidizable clement, 
Bi reference will now be made to the pre- 
Fi ferred oxygen furnishing or storing cle- 
Hy ment of the cell. I have discovered by 
i experiment that the lower oxides of nickel 
fj and cobalt when in contact with a con- 


f structed an oxygen-storing element capa- 


i ble of great capacity, of light weight and 


% of high permanence. Neither the oxide 





way by: oxidizing the monosulphide in an- 


of nickel nor of cobalt is :ppreciably solu- 
ble in an alkaline .clectrolyte, and: both 
nickel and cobalt :give:nearly the same 
voltage in use; but since nickel is less ex- 
pensive than cobalt I prefer to use the 
former element for the purpose. ‘The 
preferred process for making the oxygen- 
storing clement consists in first precipitat- 
-ing either the monoxide or black hydrated 
dioxide. of the: metal—say nickel—in the 
usual'way,iwashing the precipitate free 
from.the products of the reaction; filter- 
ing off the liquid and drying off the pre- 
eipitate. The resulting dried hydrated 
oxide is then powdered very fine and is 
ready for use, ither oxide may be used 
with the same results. ‘The process above 
outlined applies to cobalt as well as to 
nickel. About seven parts, by weight, of 
the finely powdered hydrate and three 
parts, by weight, of flake graphite are then 
‘intimately mixed and moistened with a 
small quantity of a strong solution of 
potassic hydroxide, so as to dampen the 
mass, which is then inserted in the pockets 
or receptacles of the proper plates in small 
quantities at a time and thoroughly 
tamped at edch accession. Finally’ the 
mass is covered with a Jayer of asbestos, 


‘held in place by a plate of nickel secured 


in position by nickel wires, as I have de- 
scribed in explaining the make-up of the 
oxidizable element. The plates, the pock- 
ets of which are thus supplied with the 
mixture of the hydrated oxide and graph- 
ite, are then immersed in a solution of 
potassic hydroxide in water and subjected 
for a considerable time to an oxidizing 
current of about 50 milliamperes per 
square inch of surface, during which the 
oxide is either raised to a higher stage of 
oxidation than the black oxide (Ni,0;) 
or else acts as an absorber of oxygen in 
some manner unknown to me. Whatever 
the action may be, the oxide so treated acts 
as a most efficient oxygen-storing element 
for commercial use in a galvanic battery. 
The object of employing graphite, which 
is not affected by electrolytic oxidation, 
is to offer a great extent of surface against 
which the whole of the oxide is in con- 
tact, a large conducting surface being nec- 
essary, since the electrolytic reduction and 
oxidation for practical purposes only ex- 
tend a small distance from the conducting 
surface against which the oxide is in con- 
tact. This is admirably effected by the 
use of graphite in its micaceous form, the 
proportions indicated being such as to 
practically insure that the electrolytic 
action need not penetrate a greater dis- 
tance from the contact surface than the 
thickness of a’ single particle of the 
powdered oxide. - Furthermore, there-is no 
local action between the nickel.or cobalt 





oxides and the graphite. The reason: why 
nickel hydrate is preferably used instedd 
of other compounds of nickel is that the 
metal ‘itself when finally divided (as ob- 
tained by reducing a nickel compound by 
hydrogen or electrolysis) is not oxidizable 
to any considerable extent when subjected 
to electrolytic oxidation in an alkaline 
solution. ‘I'he sulphide of nickel is not de- 
composed by electrolysis under the.condi- 
tions of battery work, and the sulphide of 
cobalt only imperfectly. Hence the hy- 
Grates are the most available compounds 
for use, since they do not become inert to 
the same extent as hydrates of the oxides 
of iron after drying, they are easily pre- 
pared, and by absorbing the solution they 
swell within the pockets or receptacles so 
as to insure intimate contact and stability. 
During the charging of the cell the absorp- 
tion of oxygen by the oxide of nickel or 
cobalt causes the oxide to further swell 
and bulge the pockets or receptacles out- 
wardly, and on discharge 2 proportionate 
contraction takes place. In order that the 
walls of the pockets or receptacles may al- 
ways maintain the desirable intimate con- 
tact with the active material, the pockets 
are, as stated, made of some highly elastic 
metal, such as hard rolled sheet nickel, so 
that at each contraction of the mass the 
pocket walls will by their elasticity keep 
in contact therewith. Having constructed 


the two elements of the battery as above’ 


explained, they are preferably utilized to- 
gether in a solution of 25 per cent of 
potassic hydroxide in water and the cell 
is ready for use, and when charged the 
iron is in the metallic form and the nickel 
or cobalt oxide is raised to the superperox- 
ide stage described, : 
“Owing to several’ obscure reactions 
which take place when the battery is dis- 
charged, and also to a change of resistance 
within the electrodes, the voltage is varia- 
ble; but the average voltage over the whole 
discharge is about one volt, rising as high 
as 1.32 volts, and sometimes higher, when 
freshly charged. My improved battery 
can be overcharged, fully discharged, or 
even reversed and charged in the opposite 
direction without any injury. Over-gas- 


- ing does not disturb the initial state of 


the materials in the pockets, all the ingre- 
dients are insoluble, the supporting plates 


‘are unattacked by electrolytic oxidation, 


and the whole operation is independent of 
the strength of the solution, so that the 
battery is of great permanence, while at 
the same time more energy will be stored 
per unit of weight than with any perma- 
nent practical combination heretofore sug- 
gested. I have constructed o battery as 
above described which gives an available 
storago capacity of one horse-power-hour 
for 73 pounds weight; but it may be 
made lighter without destroying its per- 
manent character. The specific magnetic 
metals are iron, nickel and cobalt. By the 
expression “oxide of ‘a specific magnetic 
metal other than iron” as employed in my 
claims, I mean oxide of nice oxide of 
cobalt or 2 combination of such oxides. 
By the use of that expression it is my pur- 


ose to embrace and include generically *

carcély had the copper-cadmnium accumulate 
agian to the world, not without much en 
from the technical and lay press, when appeared, i §

tion, Yet this is already a giant child. Wi iit 
grow to man’s stature? Possibly, Still, it Ai 
hardly become a ‘Titan, capable of completely revol ut 
tionizing the science of accumulator manufacture. 7 

The principles underlying the new cell have a 
ready been describ:d ina paper by Dr. Art hur a 
Kennelley, read beture a meeting of the Americal 
Institute of Electrical Engineers on. May 2tst. 

Since the date of this paper later details lave ap- 
peared, obviously emanatiny from the inventor him- 
self, and going further inv, particulars, ; 

At discharge, as well a. in the previous charge, 
the voltage of this cell is 1.5 volts, maintaining a 
mean pressure of 1.1 yoits. The normal current 
density of discharge is .93 ampere per square deci- 
meter of active surface, the capacity being 30.85 
watt-hours per kilogram of cell weight, whereas 
the modern lead accumulator gives only 8& to 13.23 
watt-hours for the same weight. 


In a normal discharge through 3.§ hours the out-, 


put is 88 watts per kilogram; for one hour the out- 
put.is 26.40 watts, The cell docs not appear to be 
injured by overcharge or discharge, but suffers only 
a decrease in efficiency. 

The active material is prepared in the form of 
rectangular briquet., 7.6 by 1.27 centimeters in area, 
formed under a pressure of 30 tons per square 
decimeter, and placed in boxes of perforated sheet- 
steel, nickel-plated and of 0.075 millimeter thickness. 
These boxes are then fastened in a strong sheet- 
steel grid, 0.61 millimeter in thickness, and likewise 
nickel-plited. The whole arrangement is finally 
subjected to a hydraulic pressure of some 100 tons, 
so that, on the one hand, the retaining: boxes are 


cemented tightly, and, on the other, their side walls. - 


are bent securely about the supporting frames of 
the steel grid. P 

For automobile batteries such grids are made of 
2.5 millimeters thickness and the steel cases 0.50 
millimeter thick. The whole is placed in vessels 
also of steel, cemented by a solder capable of resist- 
ing alkaline solutions. , 

Whereas in lead accumulators the weight of the 
acid solution represents about 44 per -cent,. of the 
active mass (including, of course, the supporting 
metal), or some 25 per cent. of the fotal weight, 
in the nickel-iron cell the electrolyte is only some 
20 per cent. of the weight of the plates, or about 
14 per cent. of the total weight, since in the dis- 

- charge here no ion of the electrolyte combines with 
the active material, as in the ordinary accumulator 
SO. combines with the Pb. The amiount of clec- 
trolyte required is therefore much less, The specific 
gravity of the electrolyte, moreover, can alter essen- 
tially only through evaporation. On this account one 
may use the Edison accumulator as a dry battery. 
The expansion and contraction of the'active material 
is allowed by the elastic nature of the retaining boxes, 
and good contact between the two is always insured. 

The electromotive force of the cell appears to be 
nearly equal to that reckoned from the heat of com- 
bination of iron and oxygen, so that the superoxide 
of nickel is nearly neutral, as the nickel compound 
has only a small affinity for oxygen, in spite of the 
fact that the superoxide in the cell appears to be 
completely stable, 3 

The new cell seems to be unharmed by low tem- 
peratures, None of the constituents are taken up by 
the electrolyte or dissolved, Hitherto no polariza- 
tion has been observed, since the electromotive force 
is below that required for the disintegration of 
water, ‘The cell can be completely discharged and 


RG is 


On'th er hand,.I have obtained with or 
nary traction cell of 12.75 kilograms weight a dis- 
charge of 260.04 watt-hours for 2.5 hours; i, ¢, 20.39 
watt-hours per kilogram. With this, maybe com- 
pared the results -which Kennelly: gives—fhat : the 
modern lead cell furnishes but 8.8 to 13.23 watt-hours 


ilogram weight. F 
per kilog rhotir discharge the energy output of the 


3 erey 
abave cell is certainly somewhat increased: But we -- 


i ntine our. attention to the 20.39°-Watt-hours, | 
Tis “vould be furnished by a discharge current of 
48 amperes and with 48 square decimeters of active- 
electrode surface.. The current density, then, is one 
ampere, For the above output, then, 375 square 
decimeters per kilogram of cell weight is required ; 
i.e, about 30,85 watt-hours, With the ordinary lead 
accumulator, 5,67 square decimeters of clectrode 
surface per kilogram of cell weight is required, as 
against nine square decimeters in the Edison ar- 
rangement, or not far from the half, ¢ 

A battery to furnish a given amount of electric 
energy must then, if one employ the superoxide of 
nickel-iron elements, be nearly twice as Jarge— 


whether we figure by the dimensions of the cells ‘or . 


their number—as that required if one use the perox- 
ide of lead elements, -— : 

Tn general, with traction batteries one would seck 
to increase the number of cells, since the motor in 
automobiles requires a definite voltage, and the avail- 
able potential i the Edison accumulator, 1.1 volts, 
is only about one-half that from well-known traction . 
cells, which furnish 1.95 to 1,97 volts, That .this 
almost double space required could be allowed in-au- 


tomobiles without an increase of the dimensions -|,.° 


all around, is very much in doubt, . 

That by the new combination a great economy of 
weight over that hitherto required will be realized 
must be doubted, since the specific gravity of nickel 
and of iron amounts to about two-thirds that of lead 
(nickel, 8.5 to 89, steel 7.6 to 7.8, lead 11.37, and 
Icad-peroxide only about 7),- 7 Be adidade 

Over-charging and over-discharging do not greatly 
harm the new automobile lead accumulator, if not 
made a usual practices" From cells of this descrip- 
tion, and of 48 amperes’ rating, I Mave taken from 
150 to 250 amperes, for periods varying from short 
intervals to two minutes, and have been unable to 
detect a decrease in their capacity, after careful res 
charging, eer, 

Iu statements thus far appearing it, is not made 
certain that the superoxide of nickel-iron combina- 
tion can stand currents of such abnormal strength. 
And, indeed, not without reason. The currents fur- 


nished cannot’ be so heavy as.those from the lead. |: 


peroxide-lead clement, since the resistance of the 
alkali-solution is greater than that of the sulphuric- 
acid solution, and the porosity of the active mass 


can scarcely equal that in the ordinary cell, Espe-| . 
cially are the positive electrodes of, the Edison ac- ' 


cumulator much too compact, : 
From what has thus far ppeared concerning the 
construction of the plates o 


tailed than in the old type. Edison himself indi- 


rectly assents to this, since he hopes, by improved |. 


methods of manufacture, only to be able to furnish 
electric energy at the same price as from the existing 
types. * 

» Kennelly’s figures as to the weights of solution 
required in the Jead accumulator are from. 10 per 
cent. to five per cent. too high. On the other hand, 
his estimates for the Edison cell are too small; 
since the iron in alkali solution is not inactive 
throughout, but, as soon as it js made the anode in 


discharge, enters into the solution to a considerable |: 


extent, 


Experience must demonstrate whether the active|’ 


material in the briquets is always kept in good con-

F hot penctrate a greater distance from the contuct-surtice 
than the thickness of a single particle of the powdered

The renson why nickel hydrate is preferably ted 
Instead of other compounds of nickel Is that the met!

Ato electrolyte oxidation in an alkaline solution. The 
sulphide of nickel Is not decomposed by electrolvsls 

sy} under the conditions of battery work, and the sulphide 
of cobalt only Imperfectly. Mence the hydrates are 
the niost avallable compounds for use, since they do

plated with nickel it may be used satisfactorily for the construction 0 
either the plates or the frames, Obviously the frames 3 ber 4 Hs 
be, and in some instances preferably are, constructed of hard rubber 
or other inert material, to which the perforated sheet is riveted, as 
explained. Secured to one or both of the sides of the plate are a 
number of insulated spacing blocks 5 § to prevent adjacent plates 
from touching when immersed in the electrolyte. - 

In the manufacture of my new oxidizable element for use in a ree 
yersible galvanic cell I first preferably take monosulfid of iron a 
reduce it by a crushing operation until the particles thereof may : 
passed through a screen having about 40,000 openings per square inch, 
and I intimately mix about cight parts, by weight, of the powdered 
monosulfid with about two parts, by weight, of flake graphite of a size 
considerably larger than the perforations in the walls of the pockets 
or receptacles, Flake graphite being exceedingly thin and of large 
area gives an extensive conducting-surface in proportion to its bulk 
and weight. This mixture is then moistened with a 20 per cent solu- 
tion of potassic hydroxid, and the dampened mass is packed ‘into the 
pockets or receptacles of the proper plates by a suitable tamping-tool, 
Owing to the want of flexibility of the graphite, the mixture packs to 
a hard porous mass. The effect of electrolytic gasing therefore docs 
not disintegrate the mass as a whole when properly compressed. After 
each pocket or receptacle has been tightly packed with the mass al- 
most to its top a wad of asbestos fiber 6, about a quarter of an inch 
in thickness, is introduced into the pocket or receptacle above the 
mass, and on top of this packing is placed a strip of sheet-nickel 7, 
entirely covering the asbestos and filling the mouth of the pocket, 
which strip is permanently secured in position by nickel wires 8, 
threaded through the openings near the top of the pocket, as shown 
particularly in Fig. 2. The element thus formed is subjected to 
electrolytic oxidization in a solution of potassic hydroxid, whereby 
sulphur will be set free and combining with the alkali forms a sulfid 
of potassium, which diffuses out of the mass, while the iron is con- 
verted to a ferrous oxid thereof, This diffusion of the alkaline sulfid 
out of the plate is hastened and facilitated by subjecting the contents 
of the plate to alternate oxidization and reduction by alternately re- 
versing the oxidizing current, and by several of these operations the 
whole of the sulphur will be eliminated and the element will be ready 
for use after the iron has been reduced to the metallic state. Since 
iron does not decompose water, there will obviously be no local ac- 
tion between it and the graphite. The oxid formed from the sulfid 
increases in bulk and being intermediately mixed with the graphite 
produces considerable pressure on the walls of the plate, which pre- 
vents any disturbance of the initial state of the mass even when it is 
subjected to strong gasing within the pores by overcharging the cle~ 
ment electrically, The object of using the monosulfid is to secure 
the greatest amount of iron oxid in the smallest space and in a form 
capable of being reduced to the metallic state electrolytically. 

My attempts to utilize iron as the oxidizable element in an alkaline 
reversible battery were for a long time frustrated’ by the facts, de- 
termined only after exhaustive experiments, that dried oxids or iron 
were not reducible to any extent by the current; that spongy iron re- 
duced by hydrogen from different iron‘salts was not oxidizable to 
any considerable extent by the current; that the hydrates of iron 
were very bulky and difficult of use without drying, which operation 
effected some obscure change therein to render them nearly inert in 
the presence of the reducing current; that butky ferric oxid was not 
capable of any considerable reduction by the current, and, finally, that 

ferrous oxid, though easily reducible, was very difficult to prepare on 
account of atmospheric oxidation. The formation of the ferrous oxid, 
in the first instance, within the pockets or receptacles did away with 
the objections due to the bulk of the hydrates, while the oxid thus 
formed in perfectly reducible by the current. Instead of forming the 
oxid in this way by oxidizing the monosulfid in an alkaline solution, 
it will be obvious that salts or iron, like ferrous chlorid, may be packed 
with the graphite and when placed in an alkaline solution form chlorid 
of the alkali and ferrous oxid of iron, the alkaline.chlorid diffusing 
out of the mass. The results, however, are not so good as when the 
sulfid of iron is used, since the quantity of finely divided iron pro- 
duced thereby is considerably less and is also less porous, offering, 


therefore, a reduced opportunity for the solution to penetrate the 


mass and lowering in consequence its current-conducting capacity, 
Metallic iron, even when finely divided, as produced by clectrolytic 
reduction, does not of itself oxidize in solutions of the fixed alkalies, 
and the oxid of iron is not appreciably soluble. Compact, dense or 
non-porous iron, i. ¢., iron having relatively large particles, when sub- 


j owerful electrolytic oxidation forms a small quantity of. 
cnr fartale of the alkali and dissolves in the electrolyte. , On aa 
other hand, finely divided iron obtained as described wien, subjecte 
to electrolytic oxidation docs not form a soluble ferrous oxid. My 
improved oxidizable element is therefore absolutely Tere so 
that in the operation of the battery. the electrolyte is not changed at 
any stage of the working, and absolutely no deterioration of the iron 
: kes place, ; i 

OTL aiediaiied the advantages and characteristics of and the pre- 
ferred manner of making the oxidizable element, reference will now 
be made to the preferred oxygen furnishing or storing clement of the 
cell, . : te : 
T have discovered by experiment that the lower oxids of nickel and 
cobalt when in contact with a conductor in an alkaline solution can 
be almost wholly raised from this lower to a higher stage of oxidation 
electrolytically than is possible by chemical means and that these 
higher oxids revert to a lower stage by reduction with extreme case, 
and availing myself of this fact I have constructed an oxygen-storing 
element capable of great capacity, of light weight, and of high perma- 
nence, Neither the oxid of nickel nor of cobalt is apprecifbly soluble 
in an alkaline electrolyte, and both nickel and cobalt give nearly the 
same voltage in use; but since nickel is less expensive than cobalt I 
prefer to use the former clement for the purpose. 

The preferred process of making the oxygen-storing element con- 
sists in first precipitating either the monoxid or black hydrated di- 
oxid of the metal—say nickel—in’ the usual way, washing the pre- 
cipitate free from the products of the reaction, filtering off the liquid, 
and drying off the precipitate, The resulting dried hydrated oxid 
is then powdered very fine and is ready for use. Either oxid may be 
used with the same results, The process above outlined applies to co- 
balt as well as to nickel. About seven parts, by weight, of the finely 
powdered hydrate and three parts, by weight, of flake graphite are 
then intimately mixed and moistened with a smail quantity of a strong 
solution of potassic hydroxid, so as to dampen the mass, which is then 
inserted in the pockets or receptacles of the proper plates in small 
quantities at a time and thoroughly tamped at each accession. Fin- 
ally the mass is covered with a layer of asbestos, held in place by a 
plate of nickel secured in position by nickel wires, as I have described 
in explaining the make-up of the oxidizable clement. The plates, the 
pockets of which are thus supplied with the mixture of the hydrated 
oxid and graphite, are then immersed in a solution of potassic hy- 
droxid in water and subjected for a considerable time to an oxidizing 
current of about 50 milliamperes per square inch of surface, during 
which the oxid is either raised to a higher stage of oxidation than the 
black oxid (Ni,Os) or else acts as an absorber of oxygen is some 
manner unknown to me. Whatever the action may be, the oxid so 
treated acts as a most efficient oxygen-storing clement for commercial 
use in a galvanic battery. : 

The object of employing graphite, which is not affected by clectro- 
lytic oxidation, is to offer a great extent of surface against which the 
whole of the oxid is in contact, a large conducting surface being 
necessary, since the electrolytic reduction and oxidation for practical 
purposes only extend a small distance from the conducting surface 
against which the oxid is in contact. This is admirably effected by 
the use of graphite in its micaceous form, the proportions indicated 
being such as to practically insure that the electrolytic action need not 
penetrate a greater distance from the contact surface than the thick- 
ness of a single particle of the powdered oxid. Furthermore, there 
is no local action between the nickel.or cobalt oxids and the graphite. 

The reason why nickel hydrate is:preferably uscd instead of other 
compounds of nickel is that the metal-itself when finally divided (as 
obtained by reducing a nickel compound by hydrogen or electrolysis) 


. is not oxidizable to any considerable extent when subjected to elec- 


trolytic oxidation in an alkaline solution, The sulfid of nickel is not 
decomposed by electrolysis under the conditions of battery work, and 
the sulfid of cobalt only imperfectly. Hence the hydrates are the 
most available compounds for -use, since they do not become inert 
to the same extent as hydrates of the oxids of iron after drying, they 
are easily prepared, and by absorbing the solution they swell within 
the pockets or receptacles, so as to insure intimate contact and sta- 
bility. During the charging of the cell the absorption of oxygen by 
the oxid of nickel or cobalt causes the oxid to further swell and bulge 
the pockets or receptacles outwardly, and on discharge a proportionate 
contraction takes place. In order that the walls of the pockets or 
receptacles may always maintain the desirable intimate contact with 
the active material, the pockets. are, as stated, made of some highly- 
elastic metal, such as hard-rolled sheet nickel, so that at each.con-

traction of the mass the pocket-walls will by their elasticity keep in 
contact therewith, 

Having constructed the two elements of the battery ‘as above ex- 
plained, they are preferably utilized together in a solution of 25 per 
cent of potassic hydroxid in water and the cell is ready for use, and 
when charged the iron is in the metallic form and the nickel or cobalt 
oxid is raised to the Superperoxid stage described, 

Owing to several obscure reactions which take place when the bat- 

-iery is discharged, and also to a change of resistance within the elec. 
trodes, the voltage is variable; but the average voltage over the whole 
discharge is about one volt, rising as high as 1.32 volts, and some- 
tines higher, when freshly charged. 

My improved battery can be overcharged, fully discharged, or even 
reversed and charged in the Opposite direction without any injury, 
Overgassing does not, disturb the initial state of the materials in the 
pockets, all the ingredients are insoluble, the supporting plates are 
lnattacked by electrolytic oxidation, and the whole operation is in- 
dependent of the strength of the solution, so that the battery is of 
Sreat permanence, while at the same time more energy will be stored 
per unit of weight than with any permanent practical combination 
heretofore suggested. 

T have constructed a battery as above described which gives an 
available storage capacity of one horse-power-hour for 73 lbs. weight ; 
but it may be made lighter without destroying its permanent character, 

The specific magnetic metals are iron, nickel and cobalt. By the 
expression “oxid of a specific magnetic metal other than iron” as 
employed in my claims I mean oxid of nickel, oxid of cobalt, or a 
combination of such oxids, By the use of that expression it is my 
Purpose to embrace and include Senerically both of these utilized 
oxids, 

T do not claim herein the new depolarizer ber se comprising an 
electrolytically-active oxid of nickel or cobalt, nor do I claim herein 
broadly such depolarizer when used in a battery of the improved type 
invented by me, wherein the electrolyte remains unchanged at all 
tims and wherein both the active materials are insoluble in alt condi- 
tions of use, nor do T claim herein such a depolarizer, broadly, in 
combination with any suitable oxidizable materials. In my present 
application I claim the new oxidizable element fer se and in com- 
bination with the new depolarizer, Claims, first, on the new de- 
polarizer per se; secondly, on such depolarizer when used in a battery 
of the new type invented by me, and, finally, on such depolarizer in 
combination with any suitable oxidizable element are made in my ap- 
plication for letters patent filed on even date herewith (Case No,

The Alkaline Nickel-oxide Cell, 
—— 

By Prorrssor Atnert L. Marsi, 
LTHOUGH the books on Storage batteries do not mention any 
cell which uses an oxide of nickel in an alkaline solution as a 
depolarizer, it seems that the idea is Not new, Michalowski, 
in particular, has worked in this field, and now Edison has taken up 

the task and Promises a practical Storage battery, 

Some months before Edison's nickel-iron cell was announced and 
Without knowledge of the work of Michalowski, the weiter under. 
took to use an oxide of nickel for the positive plate in an alkatine 
cell, The idea of its use in this Way was suggested by a fact first 
observed by Fischer, that a brownish black deposit separates at the 
Positive pole when an alkaline solution of nickel tartrate is clectro- 
lyzed. The formula, NiO, 2H:0, was assigned to the Product as 
the result of chemical analysis, The oxide obtained in this way is 
a strongly negative substance, producing in alkaline solution an 
cm. f of about 1.65 volts with zine and 1.35 volts with cadmium, 
The « m. £, Produced varies slightly with the strength of current 
used in depositing the oxide Coating, 

Before Proceeding further it would der briefly the 
different oxides of nickel so th: i y be had of the 
relations of each, commonly used, There 
are three well-defined oxides of nickel known, 

1. Nickelous oxide or protoxide of la NiO) is a 
green powder, turning yellow Upon heating, It oxidizes to Ni, 0. 
‘pon being heated above 350 degs. C,; and is converted to NiO again 
upon raising the temperature above 600 degs, C, 


Goe 134 

2, Nickelic oxide or nickel sesquioxide (formula Ni,O,), some- 
times but wrongly called peroxide of nickel, is a black powder formed 
by decomposing some salt of nickel, as nickel nitrate Ni(NOs)s, or, 
nickel chiorate Ni(Cl0.)s, by heating to the lowest possible tempera-| 
ture which produces the decomposition. It is also formed by the ac-l 
tion of hypochlorites Upon nickclous oxide suspended in alkaline 
solution, 

3. Nickelo-nickelic oxide (formula NiO.) is a gray metal-like 
non-magnetic solid. 

A sub-oxide of nickel (formula Ni:O) is said to exist; 

The peroxide, supposed by Edison to have the formula NiO,, and 


called by him superoxide of nickel, is formed by the action of elec Bo 


trolytic oxygen on’ nickelic oxide in an alkaline solution, 
thought to be formed by the action of hypochlorites on the hydrate! 
nickelic oxide, NiO;.3H:0. Wicke gives the coniposition as Ni,O;, 
and Bayley as NOs. When formed in the wet way a hydrate of the 
oxide results rather than the simple oxide, but in most cases it is 
necessary to consider only the simple oxide. : 

The nickelic oxide, Ni,Qs, Prepared in any way except electraly- 
tically, is inert; that is, it Produces no em. f. when opposed to zinc 
or cadmium in an alkaline solution, When, however, an electric 
current is sent through the-solution from the nickelic oxide plate to 
the cadmium, the couple becomes active. It is quite probable that the 
substance of the active nickelic oxide plate is a higher oxidation 
product, : 

The nickelic oxide Prepared electrolytically as described above is 
at the same time subjected to an oxidizing influence, so that very 
likely it, too, is a higher oxidation Product.. The fact that analyses 
of the latter gave Wernicke results Pointing to the formula NiO). 
2H0, is not remarkable, since the peroxide is very readily reduced, 
the reduction being. especially easy in the medium in which it is 
formed. The tartrate acts as a reducing agent, I find that the oxide 
layer, which is quite black while the current is passing, immediately 
Srows lighter in color when the circuit is broken, and the reduction 
Proceeds to the formation of some green oxide, NiO; but if thor- 
oughly washed while the current is passing, no considerable redttc- 
tion takes place and the product may stand ina solution of pure 
potassium hydroxide (or sodium hydroxide) an indefinite length 
of time without apparent change, 

The equation Tepresenting the discharge of the new Edison battery 
is assumed by E, F. Roeber to be 


N+ Fe= MOL RO 


It is’ more Prqbable that theoretical NiO, is reduced to NiO; 
rather than to NiO. Even at this, the theoretical weight efficiency 
of a nickel Peroxide plate is about 1.75 times that of a lead Peroxide 
plate with its required amount of sulphuric acid. Tf, however, the 
Peroxide has the formula Ni,O;, the theoretical weight efficiency 
would be less than that of a lead Peroxide plate, 

The decrease in weight of the new Edison cell is chiefly duc to the 
use of iron for the negative plate (theoretical weight efficiency about 
five times that of a lead plate with its necessary HySO,) and to the 
smaller amount of liquid required, 

A fully charged cell having zine for the negative plate may show 
an initial voltage of 1.9 Per cell, and substituting finely divided 
cadmium for the zine I have obtained a tittle more than 1.6 volts 
per cell at the beginning of discharge. Thee. m, f. in the case of the 
cadmium cell drops gradually to zero, and in order to Get 2 good re- 
turn in ampere hours a considerable Part of the current must be taken 


at less than 1 volt Per cell,

 Bdison Battery —Jumau.—An illustrated article in which fie first 
gives abstracts from Edison’s patent specification and from Ken- 
nelly’s paper. While Kennelly gives the capacity of the new Edison 
cell as 30.85 watt-hours per kilogram of total cell, the present author. 
uses the discharge curves given by Kennelly for two different dis- 
charge rates, in order to calculate the Watt-hours per kilogram 
which the cell gives out until the voltage has dropped to 1 volt. He 
~Tfinds from these diagrams that for the 4 hours 55 minutes discharge 
_ {the capacity in watt-hours per kilogram is 27.61, while for the 3 
‘}hours 10 minutes discharge it is 28.72. This is an anomaly, and there 
seems to be something wrong somewhere, as it is not likely that for 
a faster discharge the capacity is greater than for a slower one.

He then gives for comparison the corresponding values of the i 
lightest commercial French batteries, the’ Fulmen, B. G. S., Heinz, 


and Societe pour le Travail Elec, (affiliated with the Elec, Sgor, Batt, 
Co, of this country). The latter battery has the highest capacity in 
watt-hours per kilogram of cell, namely, 27.49 for a 5-hour dis- 
charge and 23.23 for a 3-hour discharge, “When comparing the cor- 
responding values of the capacity in watt-hours per kilogram of

his compound being assumed), hence on the whole, only 2.73 grams 
of active material. If one takes into account the ratio of the active 
mass to the total weight of plate, which value, according to the 
description, must be approximately equal to the same ratio in a light 
lead cell, and if one also remembers that the coefficient of the acces- 
sories (the ratio between the weight of cell and the weight of the 
plates) must be smaller-for the Edison cell, on account of the small 
- quantity of electrolyte required, one may conclude that in the latter

that the Edison cell is subjected to the same rules, If one believes 
the inventor, however, one must give up the hope of an improvement 
in this direction, as he claims to have invented the only possible 
method of making the active material.” Concerning the durability 
of the new accumulator, it is said it would be interesting to know 
whether the capacity remains the same during the whole life and 
whether there occurs a swelling of material at one pole and a con? 
traction at the other, He refers to the use by Michalowski of Ni: Os 
for accumulator plates, while Edison says that the formula of the 
oxide used by him is NiO. “To sum up, the interest of the Edison 
cell does not lie in the discovery of a new couple, but in the discovery 
of a special process of preparing material which heretofore could 
not be rendered sufficiently active. This is certainly a very impor- 
tant solution, and one not without difficulties, as one may judge from 
the considerable number of experiments which had to be made, a 
for the iron alone, the number of the compounds tried was several 
hundreds, A way has been opened to experimenters and an indica+ 
tion has been given that one should not despair of finding a mean: 

of rendering substances active which can enter into the construction 
of new accumulators.” The invariability of the electrolyte is sai 

to be a favorable condition, but not a new one, as the Jungner cell 
has the same property, The most important property of the Edisoy 
cell is the insolubility of the active substances at the end of the dis:

Theory of the Edison Nickel-Iron Cell. _ 


To the Editors of Elcetrical World and Engineer: 
Sirs—I have read with great interest the full account of the dis- 
i cussion which followed Dr, A. E, Kennelly’s Institute paper on the 
new Edison iron-nickel cell, as published in the recently issued Nos. 
'G6and.7 of the A. IE. &. Transactions, I should like to make, with 
| your permission, a few remarks on the electro-chemical theory of 
i this cell, and more especially on some points about which there seems 
ito be no general agreement, ° 
Any one who undertakes at present to develop a theory of the 
Edison cell, must, of course, rely upon the correctness of the princi- 
pal claims made by the inventor that the electrolyte is not changed 
and that the total result of a charge and of a discharge is that oxygen 






































material, and for different current densities, and there is no doubt], | 




























































































































































disappears at one electrode and that the same quantity appears at 
the other electrode, Dr. Kennelly’s statement that the cell is an 
“oxygen-lift,” seems therefore quite a happy characterization of the 
general resulting action in the cell, On the other hand, several 
speakers in the discussion, and more especially Mr, C. O, Mailloux, 
have rightly pointed out that it would be of interest to sketch the ionic 
mechanism by which the transfer of oxygen is brought about, Dr. 
Kennelly says about this oxygen transfer: “Now, the action, of 
course, by which this transfer takes place is much more complicated, 
and I have not attempted to carry it out; in fact, I do not know it. 
Unless we all kiiow accurately what the compound was and just ex- 
actly what the salt of nickel was—it is only assumed to be nickel 
peroxide—we could not attempt to map exactly the actions that oc- 
cur.” Edo not think that the latter argument can be sustained; in 
fact, there is no reason whatever to defer a discussion of the mechan- 
ism of ionic migration in the electrolyte on account of our ignor- 
ance of the exact chemical constitution of the electrodes. When we 
know what the electrolyte is and when we also know that the only 
change in the electrodes is that the one is oxidized and the other 
gives off oxygen, we possess all the Uata required to sketch the 
mechanism of ionic migration in the electrolyte. 

Indced, we are able to form an idea of what takes place in the 
electrolyte, from several points of view. For instance, from the old- 
fashioned one which lays the whole stress upon the water and as- 
sumes that it is the water which is decomposed in an aqueous solu- 
tion, with the result that hydrogen is sct free at the cathode and 
oxygen at the anode. If we could assume this to be the case in: the 
Edison cell, we would, dtring discharge, get the following reactions 
of the hydrogen and oxygen ions with the nickel peroxide and iron 


_clectrodes, respectively: 


NiO:-+ Th = NiO -+ 1,0 
Fe+O=FeO 


The nickel hypcroxide is: reduced, the iron is oxidized. Further- 
more, the equations show that when one H: jon an one O ion 
are set free at the electrodes—which represents the disappearance of 
one H.O molecule in the electrolyte—another H:0 molecule is 
formed at the nickel plate, so that the constitution, the quantity and 
the concentration of the electrolyte are not changed. 

This view leads therefore to a general explanation of the claims 
regarding the resulting action in the Edison cell. But it is, as I said 
before, based upon somewhat old-fashioned assumptions, Since the 
so-called electrolytic dissociation theory has come into fashion, we 
take a view nearly opposite to that just sketched, and assume that 
the water is inactive and that ina KOH solution, as in the Edison 
cell, it is the positive IX ions and the negative OH ions which, 
traveling with certain speeds, accomplish the transportation of clec- 
tricity through the electrolyte. A theory of the electro-chemical 
action of the Edison cell, based upon the views of the dissociation 
theory, was given by me in this journal in its issue of June 29, 1901. 
I have shown there that the general resulting action in the Edison 
cell can well be explained in this way, and I have also drawn conclu- 
sions there as to local concentration changes at the clecrodes which 
will enable an examination of this theory to be made by experiment. 

What I want to emphasize here is that the conclusions drawn in my 
former article are in no way dependent’ upon the chemical constitu- 
tion of the electrodes. The lifting of one atom of oxygen through a 
given KOH solution from one electrode to the other must be brought 
about by a certain mechanism of ionic migration, and this mechanism 
cannot depend upon the constitution of the electrodes, This mechan- 
ism must be the same in the Jungner silver-copper cell as in the Edi- 
son nickel-iron cell, It must be the same whether the chemical con- 
stitution of the nickel electrode at the start of discharge of the Edi- 
son cell is NiO: or Ni: Os, or something else—if only the resulting 
action is the disappearance of one, atom of O at this plate. It must 
be the same whether NiO, is reduced to Ni O—as I had assumed, in 
order to write the equations in a convenient “and easy way—or 2 NiO, 
to Ni: OQr—which Professor A. L, Marsh considers to be more prob- 
able (EvectricaL Wortp anp Enateer, July 27). As I have said 
in my former article, the conclusions drawn there regarding the pro- 
cesses in the electrolyte, are independent of the nature of the clec- 
trodes—always supposing, of course, that the only change in the 
electrodes is the transportation of oxygen from the onc to the other. 

White the mechanism of the ionic migration and the phenomena 
immediately resulting therefrom, such as local concentration changes 
at both electrodes, do not depend upon the chemical nature of the 
electrodes, the latter is of importance for the ¢. m. f. of the cell, 


For, if we neglect the small correction term, due to the coefficient of 
the e, m. f. of the cell, we can calenlate the ¢, m, f. from the heat- 
toning of the resulting chemical action by means of Thomson's rule. 
Thus, if we assume that the resulting chemical reaction in the Edison 
cell is 

NiO,-+ Fe=NiO+FeO, 


the em. f, of the cell corresponds to the difference of the formation * 


heat of Fe 0 (from Fe and O) and the formation heat of NiO: 

(from NiO and O). If, however, the chemical reaction is 
2NiO.-+ Fe= Ni: Os-+- FeO, 

the em. f. corresponds to the difference of the formation heat of 

FeO (from Fe and Q), and the formation heat of 2NiOs; (from 

NizOs and O), Should, however, the nickel compound at the 

beginning of the discharge not be NiO. at all, but perhaps 


+ Ni: Os, and the resulting chemical reaction 


Ni, O:-+- Fe=2NiO-+ FeO, 
the cm. f. corresponds to the difference of the formation heat of 
FeO (from Fe and O) and the formation heat of Ni:Os (from 
2NiO and O), 

Only for the third of these three cases are the numerical thermo- 
chemical data available, The formation heat of Fe O corresponds 
to 1.47 volts. According to Michalowski, the combination of 2 NiO 
and O to Ni; Os is an endothermic reaction, corresponding to —o.04 
volt, The e. m. f. of the nickel-iron cell would therefore be i.47 
—(—0.04) = 1.47 -- 0.04= 1.51 volts. The initial voltage of dis- 
charge of the new Edison cell after recent charge is given by Dr. 
A, E, Kennelly as 1.5 volts, The question which of the above re- 
actions—or, perhaps, still another=-takes place in the Edison cell, is 
also of importance for calculating the weight of active nickel com- 


_ pound required for a given number of ampere-hours, as has been 


pointed cut by Professor Marsh, 

I should like to take this opportunity to make a few belated re- 
marks on the editorial in your issue of July 6 in which you have 
been good enough to discuss my article in the preceding issue, You 
say that “Superficial concentration changes would necessarily occur 
by the electro-chemical combinations formed, even if the ions did not 
move past one another.” This is exactly correct so far as it goes, 
but it is insufficient for the complete calculation, as will be seen at a 
glance, when one considers the two equations which I have given for 
the reactions at the two electrodes: 

NiO, -+-2K+H,0O=Ni0+2KOH 
Fe-+-20H=FeO+H:0 

These equations show that there disappear from the electrolyte 2 K 
ions and 20H ions which represents the disappearance of 2 KOH 
molecules from the electrolyte; further, on account of the chemical 
combinations formed at the electrodes, there disappears at the nickel 
plate one H:O molecule, and there are formed 2 KOH molecules at 
the nickel plate and one HzO molecule at the iron plate. We know 
exactly. where the Jatter changes take place—those which are due to 
the chemical combinations formed at the electrodes,” But from the 
above equations, we cannot say the exact locality where the two 
KOH molecules disappear in the electrolyte which furnish the two K 
ions and the two OH ions set free at the electrodes, To complete 


the calculation, one must have recourse to the experimentally de- 


termined “transport numbers,” as I have done in my former article. 

In another part of the editorial you say that “while variations of 
concentration tend to occur at the electrode surfaces during charge 
and discharge, yet owing to the thinness of the solution layer these 
variations’ can readily cancel and annul cach other by diffusion,” 
This statement in this form scems to me misleading. “Surface” of an 
electrode, in the electra-chemical sense, is not only the outside visible 
surface, but includes also any part of the electrode at which clectro- 
chemical action takes place. The outside visible surfaces of two op- 
posite electrodes are very near together in the Edison cell, In the 
beginning of the discharge the molecules of the iron and nickel com- 
pounds in these outer layers will be oxidized and reduced and con- 
centration ‘changes tending to develop there may easily annul another. 
But when the discharge goes on, the outer layers of the active masses 
will have been oxidized and reduced, respectively, and the seat of 
clectro-chemical action (the “surface” of the electrodes in the clec- 
tro-chemical sense) will be transferred into the inner purts of the 
porous active masses. Concentration changes will then develop in 
the electrolyte in the pores of the active masses, and these concen- 
tration changes cannot so easily cancel cach other. 

Although, for the reasons given in my former article, T believe 
that diffusion acts quicker in the new Edison cell than in the lead

can annul one another, the electrolyte must Pass through the outer 
Pores of the active masses which act somewhat like a diaphragm. It 
is a well-known experimental fact that when a lead accumulator has

tion of the electrolyte between the plates increases for quite a while. 





DYNAMOS, MOTORS AND TRANSFORMERS 
Commutating Dynamo Machinery—Honart.—An abstract of his 
Glasgow Internat. Eng. Congress paper on “Modern commutating 
dynamo machinery, with special reference to the commutation limits.” 
One persistent error has bee the assumption that the kilowatt out- 
put should be given predominating consideration in laying down the 
lines of the design, and that the required voltage and amperage are 
of altogether minor importance. Machines of different voltages, but 
for the same kilowatt output have, however, one set of features in 
common, namely, the mechanical design in general. He describes a 
group of machines designed with due regard not only to these feat- 
ures of mechanical similarity, but also to the points where the de- 
signs should diverge in order to suitably comply with the require- 
ments of different voltages and current ratings. In these machines 
the base, stands, bearings and shaft are the same for all voltages, but 
while in the low voltage design the electromagnetic part of the ma- 
chine is extremely narrow and the commutator wide, the high volt- 
age machine has precisely the opposite characteristics, Since, how- 
ever, the diameter of commutator, armature, field bore and magnetic 
yoke, are the same for all voltages, it is quite practicable to use to a 
Great extent the same drawings and patterns for all voltages, the 
patterns being extended or not, according as castings for machines 
of the one or the’ other voltage are required. It is shown how 
naturally all this works out, and the opinion is put forth that by the 
use of these principles the best results for a given outlay may be ob- 
tained. Incidentally, the assertion is made that Iow reactance volt- 
age greatly outweighs in importance low armature strength so far as 
telates to excellence in commutation, and high commutator peripheral 
speeds are advocated on account of the very great improvement in 
commutating constants which are thereby rendered practicable. 
Careful attention to all these different considerations still permits 
of a fair degree of interchangeability and uniformity in the designs 
for different voltages of the same kilowatt otttput. He discusses in 
detail his method of estimating the reactance voltage. Incidentally, 
he remarks that the inductance of a coil Jaid upon the surface of a 
smooth core armature is, with customary proportions, rarely much 
Jess than one-third and often one-half or more as great-as in the 
case of the same coil laid in slots. He considers the case of large 
and states that by the use of 
high armature reaction—as expressed in armature ampere turns per 
pole piece, and high commutator Peripheral speeds, even 6o0-volt

of the armature. It is bounded by the peripheral surface of the arma- 
ture, the surface of the core at the bottom of the slots and the ends 
of the core. An examination of the machine in the terms of the 
energy generated in this “active belt” leads to the interesting result 
that machines of very widely varying size, output and speed, give a 
remarkably constant value in watts generated per cubic centimeter 
of active belt at unit velocity-in unit field, This value he believes to 
-be about 0.0000005, or 5 ergs per second per cubic centimeter at unit 
velocity in unit field. The greater Part of the paper is chiefly mathe- 
matical and cannot well be abstracted, Regarding the cost, he finds 
that in the case of many groups of machines there is no regular 
ratio between the cost and the output. There ought to be, however, 
and the following method is suggested for obtaining this result: 
Plotting watts per revolution as abscissas and costs as ordinates, the 
position of each machine is marked, and the points representing cost 
and output for each carease of a given diameter with varying length. 
are joined by a straight line which is produced to the origin. The 
point where this line cuts the zero ordinate gives the limit of cost to. 
which this carcase approaches as the core length is réduced to zero, 
and may be called the base cost of any given carcase. An increase jm 
diameter increases the base cost and reduces the slope of the line 
passing through the costs of the actual machines, so that, starting 
from the smallest diameter and passing to the largest, will give a 
succession of straight lines, each touching its next lower neighbor at 
one point, and producing a curve made up of segments of the lines. 
representing each machine, each segment showing the economical 
range of length for the machine which it represents—Lond. Elce.,.

: Edison Battery.—De Contanes.—An illustrated article on the new 


| Edison accumulator. After an abstract of Kennelly's paper the fol- 
lowing critigal remarks are made, The Edison accumulator is said 


a discharge rate of 0.93 ampere per square decimeter. This is com- 
_.{ pared with the capacity of a modern Fulmen lead cell, which for a 

discharge’ rate of t ampere per square decimeter “has a capacity per 
electrode” (this probably means per kilogram of electrode) of 22.5 
ampere-hours, at an average voltage of 1.9 volts, hence 42.75 watt- 
hours, (This comparison is very unfair, From Kennelly’s paper it 
| is evident that 30.85 watt-hours is the capacity of the Edison cell 
per kilogram of total cell, not per kilogram of electrode). He then 
| gives a comparison of the Edison cell and a modern lead cell, with 
reference to the weight of the electrolyte and finds an advantage in 
favor of the lead cell. (This is evidently wrong. He says that the 
: é weight of the electrolyte in the Edison cell is 14 per cent of the weight 
“.. . st | of the electrodes, while according to Kennelly’s paper it is 14 per 
oe ‘| cent of the total cell weight). He further says that the Edison cell 
will be expensive, and believes that it will not be durable, (One of 
the principal claims of Edison is that there is practically no de- 


terioration).—Cosmos, July 6, 
Edison Battery—Kriecer—A communication in which he says 











that he has used nickel for positive accumulator plates before Michal- 


ieee x battery in 1896. The ec. m. f. was experimentally found to be 1.82 
volts, which corresponds exactly with the theoretical value if the 
chemical process at the nickel plate is assumed to be the change of 
the peroxide of nickel into nickel oxide —L’Ind, Elec., July 10. (See

black oxide, CuO, and finally electrolytically reduced to the metallic 
state, So prepared, it is oxidized in charging the battery to the red 
oxide Ci,0, but shows no tendency to pass into solution. It is. dif- 
ficult indeed to believe that this remarkable effect is properly at- 
tributed to the state of minute sub-division ; if so, the fact is unique 
in chemistry. 

The second difficulty—the deposition of spongy zinc--is overcome 
by the simple expedient of using as a base for the clectro-deposit a 
thin multi-perforated sheet of magnesium, If it be assumed that the 
tendency of zinc to deposit in sponge form is duc to the partial oxi- 
dation of the precipitated metal, then it is readily apparent that the 
nature of the support may exert a controlling influence on the char- 
acter of the deposit, and that magnesium, being electro-positive to 
zine and entirely unattacked by the caustic alkali, can give rise to no 
Jocal action, and therefore to no oxidation due to this cause. This is 
the explanation of the inventor. It is not free from chemical dif- 
ficulties, for other means may be employed to prevent local action, 
and yet these have not proven efficient in suppressing the formation 

of sponge; but the essential commercial point—the fact—seems to 
have been sufficiently establishd by Mr. Edison's experimental work. 

In the accompany illustrations, Fig. 2 represents a plan view 
of the magnesium support on which the zinc is plated during the 
charging, a similar view of the plate for carrying the negative ele- 
ment, and a vertical section through a cell formed of four elements, 

In Fig. 1 are represented similar views of another form of cell, 

showing a plan view of one of the magnesium supports on which the 

zinc is plated during the charging operation, a similar support for the 
depolarizing material, a section of the latter on an enlarged scale 
and a section through a four-clement cell.

ELECTRO-CHEMISTRY-AND’ BATTERIES, ~~~ 
| Edison Battery —De Contaves.—An illustrated article on the new 
Edison accumulator. After an abstract of Kennelly's paper the fol- 
lowing critica) remarks are made, The Edison accumulator is said 
to have a capacity of 30,85 watt-hours per kilogram of electrode, for 
a discharge rate of 0.93 ampere per square decimeter. This is com- 
pared with the capacity o€ a moder: Fulmen lead cell, which for a 
discharge’ rate of 1 ampere per square decimeter “has a capacity per 
electrode" (this probably means per kilogram of electrode) of 22.5 
ampere-hours, at an average voltage of 1.9 volts, hence 42.75 watt- 
hours, (This comparison is very unfair. From Kennelly's paper it 
is evident that 30.85 watt-hours is the capacity of the Edison cell 
per kilogram of total cell, not per kilogram of electrode). He then 
gives a comparison of the Edison cell and a modern lead cell, with 
reference to the weight of the electrolyte and finds an advantage in 
favor of the lead cell. (This is evidently wrong. He says that the 
weight of the electrolyte in the Edison cell is 14 per cent of the weight 
of the electrodes, while according to Kennelly’s paper it is 14 per 
cent of the total cell weight). He further says that the Edison cell 
will be expensive, and believes that it will not be durable, (One of 
the principal claims of Edison is that there is practically no de- 


terioration).—Cosmos, July 6.

that he has used nickel for positive accumulator plates before Michal-

This will give a fairly large diameter of the rotor (in the motors al- 
ready constructed about 9 cm., or 3% inches), and there remains 
for the primary core considerable depth in the radial direction with 
the assurance of a low saturation. The rotor in this manner will 
have a diameter of 780 mm. (30.7 inches), while the over-all diameter 
of the motor is 1050 mm, (41.3 inches). 

The motor is so wound that the primary pressure of 1150-1850 
volts is carried to the rotor of the motor. For this purpose three 
collector rings are affixed at one end, which are made of good bronze 
and are insulated from each other by mica sheets which project con- 
siderably, as seen in Fig, 14. Eight carbon brushes make contact 
with each of the rings. The brushes are fed forward by means of 
springs, and in order to keep the brush holders a considerable distance 
apart from each other, they are distributed all around the periphery. 
They can be reached from the outside through small holes, 

The core of the rotor consists of a number of iron plates, cach of 
which is stamped out of a solid piece of shect iron and all the plates 
‘are firmly held together. 

The winding of the rotor, Fig. 14, is of the continuous-current bar 
winding. type, as in this winding the ends of the various coils may 
be best protected from the action of centrifugal force by tightly- 
wound wire bands, The slots are insulated by means of mica, and 
wooden wedges protect the coils from flying out. 

The winding of the stator is of the ordinary alternating-current 
type, and the core consists of a number of separate iron sheets joined 
together. The three primary and secondary leads are insulated from 
the frame wherever they pass through it by rubber bushings, Fig. 15

Automobile Storage Batteries, 





} E present herewith descriptions in detail of a number of stor- 
age batterics now available for automobile work, the descrip- 
tions having been prepared from information furnished by 

the manufacturers of the various batterics considered, The state- 

ments of performance thus come from the makers themselves, and 
while we do not doubt that all claims are’ made in good faith, due al- 
lowanee must naturally be made for ‘ultra-conservatism on the one 
side and enthusiasm on the other, The information herewith given, 
however, is substantially within the range of fact, and presents in 
concise form the main differences between the batteries considered. 
With a few exceptions all of the American automobile batteries now 
on the market are described, only a few manufacturers having denied 
the request for information concerning their products. The Edison 
storage battery is not included for the reason that a description of it 
has recently appeared in these columns, and no further information 
is available relating to its construction and performance, ; 
As will be noted, data of a number of the batteries have been ‘re- 
duced to the basis of a three-hour discharge. Not too much stress 
should, however, be laid upon a comparison of different batteries on 
this basis in the absence of information as to corresponding durability. 

In other words, such a comparison is not conclusive unless each bat- 

tery is designed with a view to give efficient results at that particular 

rate of discharge. 
TITE SPERRY BATTERY, 


‘The Sperry battery is sin improved form of the Planté type of lead- 
lead battery, but so designed and constructed as to be free from the 
difficulties that have attended the use of the applicd sponge plate. 

The grid is made of thin, pure sheet lead, which is corrugated hori- 
zontally. In the bottom of the hollows formed by the corrugations 
numbers of small trapezoidal holes are punched; the punch also cuts 





FIGS, 1 AND 2,—SPERRY BATTERY, 


diagonally across the trapezoid, and instead of making a clean hole, 
fins are left which project on either side of the plate. The whole plate 
when punched resembles a corrugated grater, except that the fins are 
loriger, and triangular in shape. These projections are then spread 
wider apart so that a pressure on the plate will cause them to bend 
down in a direction away from the holes from which the fins project. 

The material which is to become active is spread in the form of a 
powder on both sides of the grid, filling up the corrugations and be- 
ing in sufficient quantity to make a flat plate of usual thickness after 
press-welding. The whole is then subjected to pressure—about 1000 
Ibs. per square inch of surface—which forms it into a solid mass, 
The material is bound to the grid by being pressed together into a. 
continuous mass, which is on both sides of the grid and is welded 
through the multitude of small holes, thereby riveting itself in the 
grid. Additional hold is furnished by the fins, which bend down 
and are clinched over the active material and thus retain the ma- 
terial at the surface. é 

The retention of the fins and riveting under pressure of the pow- 
der into a solid mass cannot be successfully accomplished with every 
form of material to become active, but it is stated that the material 
used in the Sperry battery welds up strongly in the press, and after 
the chemical formation, becomes hard like soapstone, This active 
material consists of 80 to 85 per cent of finely divided pure lead ob- 
tained by dissolving a precipitation as explained in the description of 
the chloride battery, to which is added 15 to 20 per cent of lead 
oxide. These are thoroughly mixed, and to the mass thus formed is

gredients, 


The alkaline salts and the other ingredients are themselves inert 
and their function is twofold: First, to render the material porous 
by dissolving out when the plate is “formed,” leaving numberless 
pores throughout the mass, and, second, they have the peculiar Prop- 
erty of causing the mass to harden on forming instead of soften, as 
is the case with pasted or other plates formed by the Planté process. 

The composition of the active materiat used, its method of appli- 
cation, and the formation in the Sperry battery, are such, however, 
that trouble from disintegration and dropping away of active nae

terial is obviated, and the makers claim, and their tests seem to in- 
dicate, that the plates are extremely hard, solid and durable, The cor- 
rugation of the grid horizontally allows proper expansion and re- 
lieves the plate of any tendency to buckle. * As an additional precau- 
tion, however, Mr. Sperry has devised the pyroxylin coating which 
is applied to the outside of the plate and covers it, passing down one 
side, under the bottom of the plate and up the other side. It is 
evident that if any active material should be loosened by any ex- 
traordinary circumstances, it would not be able to drop off the plate, 
being held in position by the outside coating. If a particle of ma- 
terial should by any chance drop off, it will still be retained in the 
Ppyroxylin envelope and would not be able to short-circuit the 


an battery. 


This covering is made of open mesh cotton cloth, such as “cheese- 
cloth,” which is chemically treated, forming a cellulose nitrate which 
is termed “pyroxylin.” This compound is of the same general char- 
acter as gun cotton, which is a high explosive. The addition of a 
1 small quantity of nitro-benzol renders it inert. 

To the sheet of pyroxylin thus formed is applied a coating of 
pure cellulose. This is formed by treating fiber—in which the non- 
cellulose constituents belong to the class of aldechydes—with sul- 
phurous acid. The fiber after being washed is again ‘treated with 
@ sulphurous acid, leaving pure cellulose. This is then pulped and 
applied under pressure to the pyroxylin sheet. The envelope when 
finished is ribbed vertically so that the elctrolyte can circulate freely 
along the surface of the plate after passing through the envelope. 

The jars in which the elements are placed are of the hard rubber 
variety, but different from the usual hard rubber jar in that they

bottom of the cell. On these soft resilient ribs rest the plates which

54-hour discharge, giving at this excessive rate of discharge 4o Ibs, : 
per horse-power-hour, corresponding to an ‘energy sufficient to raise 
its own weight against gravity at sea level about 9 miles, . 

This is equivalent to 2.65 amperes, 7.95 ampere-hours, 5.03 watts | 
and 15,09 watt-hours per pound at the 3-hour rate, There are sev- 
eral sizes of these cells manufactured, the two principal ones being 
2 inches by 734 inches by r0!4 inches, and weighing 18 Ibs. gross, and 
3 inches by 714 inches by 10% inches, and weighing 22.8 ibs, 

A number of life tests have been made on this battery, both in lab- |’. ° 
oratories and on vehicles and in practical work, One vehicle has now |" 
made about 7700 miles with the batteries with a loss of 28 per cent 
-of the original capacity. Tests recently conducted under the general 
supervision of Professor John W. Langley, of the Case School of 
Applied Science, show that the battery carried through a uniform rate 
of discharge of 1 ampere per pound until the carriage had run the 
equivalent of 3060 miles. This test shows the capacity of the bat- 
tery for the last 10 discharges to be 10 per cent (83.35:.91.8) in ex- 
cess of the first 10 discharges. . The report indicates that tests up to 
this point had failed to reveal any indication that the battery had 
started to fall off in capacity. The 44th discharge of this battery, 
taking it at 1 ampere per pound of complete working cell, gives a 
mean potential difference throughout the curve, of over 2 volts, 
namely 2,014. > 
THE INTERNATIONAL STORAGE BATTERY, 


The Clare cell, made by the International Storage Battery Com- 
pany, is claimed to embody novel features of mechanical construc- 
tion, that contribute to durability, efficiency, capacity for rapid work- | 
ing, and a relatively large output of energy per pound of maerial,

THE SPERRY BATTERY. 


The Sperry battery is an improved form of the Planté type of lead- 
lead battery, but so designed and constructed as to be free from the 
difficulties that have attended the use of the applied sponge plate. 

The grid is made of thin, pure shect lead, which is corrugated hori- 
zontally, In the bottom of the hollows formed by the corrugations 
numbers of small trapezoidal holes are punched; the punch also cuts

diagonally across the trapezoid, and instead of making a clean hole, 
fins are left which project on cither side of the plate. The whole plate 
when punched resembles a corrugated grater, except that the fins are 
longer, and triangular in shape. These projections are then spread 
wider apart so that a pressure on the plate will cause them to bend 
down ina direction away from the holes from which the fins project. 

The material which is to become active is spread in the form of a 
powder on both sides of the grid, filling up the corrugations and be- 
ing in sufficient quantity to make a flat plate of usual thickness after 
press-welding. The whole is then subjected to pressurc—about 1000 
Ibs, per square inch of surface—which forms it into a solid mass. 


The material is bound to the grid by being pressed together into a. 


continuous mass, which is on both sides of the grid and is welded

The heavy ribs at the edges of the plates hold them a short distance 
Apart over that part of the surfaces where the active material is 
ocated, An acid-proof cement is applied to join the heavy ribs at 
he edges, and a receptacle containing the active material is thus 
formed by the two plates, Into the tong, narrow opening of this

mate contact with all of the cells of active material, At one side a 
trip projects from this lead sheet and serves to connect it with a 
isimilar sheet between two other plates, The pair of earthenware 
: ‘plates with active ‘material pressed into their cells, joined at their 
-fedges to form a receptacle, and the sheet of lead, form a single 
- ‘positive or negative element of the battery. The corresponding nega- 
‘ sitive or positive clement is made in exactly the same way. 

if The sheet of lead, about-1-32 inch in thickness, serves merely as 
‘Ys conductor of the current, and the earthenware receptacle supports 
_ both the active material and the conducting sheet. Two of the ele- 
‘ments described go to make up the smallest size of battery. For bat- 
teries of larger size the receptacle for each clement is made up of 
our or more of the same earthenware plates, All joints between the 
earthenware plates are made with the acid-proof cement, so that cach 
Feceptacle, however large, is a rigid structure, though made up of a 
‘considerable number of parts. 

‘| Particular attention is called to the earthenware receptacle, be- 
‘sause on its structure and on the method of supporting the active 
“material, the novelty of the Clare battery depends. In this battery 
the conducting sheet of lead does not support the active material, but 
“os itself supported by the receptacle, As the lead conductor is not 
.. ‘required to act as a support, it can be, and is, relatively very light in 
weight. The earthenware receptacle is also much lighter than a sup- 
porting plate of lead would be for the same stiffness, The earthen- 



























FIG, 7.—DISCHARGE CURVES, CLARE BATTERY, 


ware receptacles with their active material and lead conductors are 
immersed in an acid electrolyte of the usual quality, and the solu- 
tion passes freely through the porous sides of the receptacle to the 
active material, As the sides of the receptacles are very thin, being 
hardly more than 1-16 inch in thickness, and as the electrolyte flows 
freely through the grooves formed by the ribs on the outer sides of 
adjacent elements, the internal resistance of these batteries is very 
low. Active material cannot fall out of its cells in the carthenware 
plates, because the opening in the receptacle is only large enough to 
admit the conducting sheet of lead between the two surfaces where 
the conducting material is located. Experience has shown that the 
receptacles are sufficiently clastic to allow for all expansion of the 
active material withqut injury. 

Several tests of these batteries have been made by independent en- 
4) gineers, and the result of one of these is illustrated in the curve here 
presented. This test was made on a battery rated at 20 ampere-

in three hours or less, and charged in the same length of time without 
injury.

intend putting other sizes on the market within the next few months,

pere-hours at 5-hour discharge rate. 


“THE GOULD BATTERY, 


The plates of the Gould battery are made from pure rolled lead. 
These plates have their surface increased by a spinning process. 
This spinning is accomplished by clamping the plate in a special 
machine whereby it is given a reciprocating motion between rapidly 

revolving arbors carrying a series 

of disks which are forced into the 

plate, displacing the lead into a 

series of alternating ribs and 

grooves, The active surface of 

the plate is thus increased to 17 

times its area as a smooth plate. 

This pressing and displacing in- 

creases the density and homo- 

gencity of the plate, and makes it 

more durable. The spinning pro- 

cess leaves the ribs firmly con- 

nected to the supports so that each 

rib is independent and has an in- 

dependent contact with the sup- 

ports, and it is not necessary to 

depend on a center webb for con- 

ductivity. The plates are thus in 

a condition to allow of the expan- 

sion and contraction, duc to 

charge and discharge, taking place 

without loss of active material or 

FIG, 11.—GOULD CELL, damage to the grid. The plates 

are placed in a bath and current 

passed through them, whereby active material js formed from the 

material of the plates themselves, After forming, the plates are 

cleaned, washed, and all traces of the forming. solution removed, 

the plates are then assembled into elements consisting of the various 
numbers of plates, according to the capacities required. 

The principle followed by the Gould Storage Battery Company is 


Time In Minutes 
FIG, 12,—DISCHARGE CURVE, GOULD CELL, 


to increase the surface exposure as well as to increase the contact 

area of the active material with the grid, it having been demonstrated 

by their tests that by reducing the rate of charge and discharge per 

square inch of active surface, the life of the battery is increased, as 

well as its ability to stand high rates of charge and discharge. 

i The plates are therefore made as light as mechanioal considerations 
will permit, and the greatest possible amount of active surface is ob-

tained by the spinning process before mentioned. The actual active 
surface is 450 square inches Per pound of plate, which gives 250 
square inches per ampere at the 8-hour discharge rate. As the active 
oxides form in a thin adherent layer over the surface, the voltage at 


rapid discharge rates is somewhat higher than usual in lead cells, 
The thinness and porosity of the active material permits the escape of 
evolved gases without dislodging the oxides, 

The separators consist of the usual ribbed and perforated rubber 
sheet, and the jars are of the same material. These jars have, raised 
on the bottom, two heavy ribs upon which the platés rest, This leaves 
a proper space below the plates for circulation of electrolyte, and the 
accumulation of sediment. A hard rubber cover fitting into the top 
of the jar and resting on the top of the cross bars prevents splashing 
of the electrolyte. The connectors are of the usual flat top variety. 

The foregoing table gives weights, dimensions and capacities of 
the Gould automobile batteries, Type EV, dimensions of plate, 57% 
inches by 9 inches. . 

This shows that at the 3-hour rate, 1.10 amperes, or 2.09 watts, are 
-continuously available, which is 3.30 ampere-hours, or 6,27 watt-hours, 
per pound, gross weight of battery, 


. TILE CHLORIDE ACCUMULATOR, 


The general characteristics of this battery are well-known, The 
positive plate is termed “Man- 
chester Plate” by its makers, and 
consists of a grid cast of lead with 
round holes about 13-16 inch in 
diameter and 15-16 inch between 
centers, 
These holes taper to a smaller 
diameter from the outside surface 
to the middle of the plate, making 
in effect holes which are counter 
sunk, from both faces of the plate, 
The active material consists of 
pure lead which is taken in the 
form of ribbon, the width of 
which is equal to the thickness of 
the plate, and passed between two 
rollers. The periphery of the 
lower roller is smooth, while the 
upper one is toothed, the teeth cut pro, 13.—CHLORIDE ACCUMULATOR, 
into the lead ribbon making a 
ridged surface. The ribbon is then cut into suitable lengths and 
rolled into spirals, the outside diameter of which is the same as the 
diameter of the hole in the grid measured at its ‘smallest diameter, 
These spirals are pushed into the holes and tightened by expanding, 
when the plate is “formed” by charging, 
A lead ribbon which has been ridged on one surface forms, when

rolled into a spiral,.a pellet of active material which is very porous 
and allows free circulation of the electrolyte through the plate. 

The negative plates are the regular “chloride” type, made by cast- 
ing the grid around the pellets of active material, these pellets being 
placed in the moulds, This grid is of lead alloyed with a small 
amount of antimony and cast tinder heavy pressure, to insure good 
electrical contact between the pellets and the grid, and atso to make

the latter take firm hold of the pellets and obviate any danger of their

The pellets are made of finely powdered lead, which is dissolved 


in nitric acid. The addition of hydrochloric acid to the solution pre-

cipitates the lead in form of lead chloride, The precipitate after be- 
ing washed is melted with zine chloride and the fused mixture poured 
into moulds the form of the pellets. These are approximately 34 of 
an inch square, and the same thickness as the grid, namely, 4 inch. 

The finished plates are placed between zinc plates and immersed 
in a zinc chloride solution, On short circuiting the plates, the actions 
set up are such as to remove the chloride, leaving the pellet in the 
form of pure lead in a very porous state. The types manufactured 
are denominated M, FV, MV, OV, PV, QV, RV, TV, UV and SV. 
The various types of plates and cells, their sizes, capacities, cte., are 
as given in the following table:

ample to prevent the liquid from slopping over. These can only be

edges by a black composition put in in the form of fillet, one side of 
which rests on the cover and the other rests Against the inner walls 
of the cell. A small hole is made in the middle of the cover for 
ventilation and escape of gas. 

The connectors are generally U-shaped, the two ends being fas- 
tened to two sets of plates, and the bend passing over the edge of 
the jars that abut against each other. The clements in high jars are 
connected by “flap top” connectors, 

Several types of separators are used, one being made of corru- 
gated hard rubber, pierced with a number of small holes through 
which the electrolyte can circulate. In order to secure lightness, the

jars are made thin. They are sufficiently strong for rough usage 
when put together in a tray, so that the contiguous cells or sides of 
trays afford support, They are, however, not strong enough to be 
used without trays or separated from adjacent jars. The table shows 


FIG, 16,—DISCHARGE CURVE, EXIDE CELL, 


that these cells give an average of .98 ampere or 1.86 watts per pound 
gross weight at the 3-hour discharge rate. 

A new automobile battery which the Electric Storage Battery Com- 
pany has brought out, is called the “Exide Accumulator” (Fig. 15). 
No information as to principles and construction is available. It is, 
however, a form of pasted plate and much lighter than the “Chloride” 
accumulator, as will be noted from the accompanying table:

This shows that the capacity at the g-hour rate of discharge is 1.33

THE WILUARD BATTERY. 


This battery is made up of plates of the 

Planté type, which are sheets of pure lead, 

ribbed or grooved. The Willard plate is 

grooved across the width of the plate, the 

ribs not being perpendicular to its surface, 

but making an angle with it; that is, the 

cut is in a downward direction from the sur- 

: : face to the center of the plate, which viewed 

from the edge presents a “herring bone” cross section, the ribs slop- 

ing upward, These ribs are very thin and flexible, and their surfaces 

increase the active surface of the smooth plate to about 16 times its 
original area. 

On formation of the lead oxides on a positive plate, the active lead 

is expanded, and in case of rapid charge this expansion may distort 


FIG. 17,—WILLARD CELL, 


the plate and cause buckling, or the pressing out of the active oxides, 
The Willard cell, so the makers claim, is not subject to any deteriora- 
tion or buckling, as the active oxides are formed between the ribs of 
the plate and their expansion only opens out the ribs, separating them 
a slight amount from each other, The manner of “forming” these 
plates is not stated, but an examination indicates that the Process is 
chemically alkaline. 

The construction gives a plate without any joint whatever be- 
tween the active and the conducting lead of each ‘plate, as each rib 
is an integral portion of the plate. This results in a low internal re- 
sistance. The makers state that by charging 20 minutes at double 
the normal charge rate, then at one and one-half times for 10 minutes

and one-fourth capacity for 20 minutes, the battery can be charged 
within 50 minutes without any injury to or deterioration of same. 
The capacity referred to is on a basis of 1-hour discharge. 

The form of plate used permits high charging rates when the cell 
is empty. It is also stated that this battery can be made to discharge 
completely in 30 minutes without damage, though a higher rate is not

advisable. The separators are made of hard rubber, fashioned in 
the form of a sheath, They are ribbed to secure strength and per- 
forated to allow free circulation of electrolyte. 

The makers do not claim extreme lightness for their batteries, as 


FIG, 18,—WILLARD CELL AND PLATES, 


their idea is that plenty of lead is required for durability, and that 
light batteries are subject to more rapid deterioration than heavy ones. 
Their automobile battery they claim is a compromise between the 
weight necessary for durability and tightness required to prevent 
vehicles from being too heavy and clumsy. In this compromise the 


+ FIG, 19.—DISCHARGE CURVES, WILLARD CELLS, 


makers believe that they have reduced the weight of the plates to the 
lowest amount compatible with Jong life under the arduous service 
to which automobile batteries are subjected, : ; ; 

A series of curves is shown in Fig. 19, which gives, graphically, 


the relation between voltage and time of discharge of the Willard 
cell at varying rates of discharge. The uppermost curve shows this 
relation on charge at the 8-hour rate, 

The makers of the Willard battery manufacture two ‘types for aus 
tomobile service, One is designated the “Standard,” and the other 
the “Willard Special.” The accompanying tables give the data of 
the two types: 2

From the foregoing, it will be seen that the continuous output of 
the “Standard” batteries averages .96 ampere, or 1.82 watts, per pound 
gross weight, on a basis of 3-hour discharge rate, which is equivalent 
to a total output of 2.88 ampere-hours, or 5.47 watt-hours, The 
"Special" gives 1.01 amperes, or 1,92 watts, continuously for three 
hours, being a total of 3.03 ampere-hours, or 5.75 watt-hours, per 
pound gross weight. 

PORTER BATTERY, 


The construction of the Porter cell differs materially from other 


types of pasted or chemically formed lead batteries, The plate or 
grid itself for automobile work is 5 by 7 inches and ¥% inch thick. 
It is composed of an alloy or compound which the manufacturers 
state gives greater conductivity, greater resiliency and consequently 
greater working capacity than the ordinary pure lead plate, and also 
resists the action of the sulphuric acid in the electrolyte that upon 


FIG, 20,—PORTER CELL. 


lead produces sulphate of lead or the white precipitant which causes 
go much of the trouble in the pure lead types. The active material 
is secttrely held in the grid so that its greatest width isin the center 
of the plate and the smallest surface is exposed. This not only acts

asa wedge, but also allows the material to do the greatest amount of 
work with a minimum of wear, and greatly increases the Proportion 


of capacity with the surface of active material exposed, at the ratio of 
about 3% to 1, 


The active material itself is treated before being

“formed,” and the relative distances, while in the forming process, 
are increased and decreased proportionately, so that the interior is 
also formed, and not alone the outer surface, as is ordinarily the case. 

From the preceding table issucd by the manufacturers, it will be 
noted that on a high discharge, such as is required in automobile 
work, great capacity per pound weight is shown. 

All the parts of cells are standard and interchangeable, which is 
very desirable, In the method of working up the batteries, the cells 

















FIG, 21.—DISCHARGE CURVE, PORTER CELL, 


‘ are all formed of equal capacity and all work within .os volts of each 
other on an equal discharge, so that the danger from reversed cells 
on a low discharge is extremely small. The curve of Fig. 21 refers 
to a 12-Ib, cell discharging at a little over a 3-hour rate. 

The efficiency on a constant-current, constant-potential circuit, on 
a 434-hour charge, 334-hour discharge, is very high, standing a little 
above 88 per cent, the charge on a 13-Ib, cell beitig 76 amperes, and the 
discharge 67. On a constant potential graduated current the per- 
centage of efficiency in ampere-hours is very much higher, The 25-lb.

THE AMERICAN BATTERY, 

This battery is made up of elements which are formed by grooving 
pure shect lead, teaving a number of thin projecting ribs, The active 
material is clectro-chemically formed, as is usual in such batterics, 
The ribs are turned upwards, 

The plates are supported by insulators, which lift them off the 
bottom of the jar and also serve to separate the plates. The elements 
are in this way suspended, and there is left a clear space in the bot- 
tom for the circulation of electrolyte and the deposition of sediment 
without danger of short circuiting, ‘ 

Tnterposed between the insulators and positive plates are thin per- 
forated sheets of hard rubber which are put in as an additional pro- 
tection against contact of plates and consequent short circuits, 

The separation between the positive and negative plates is some- 
what greater than is usual in lead batteries, being a full quarter of 
an inch, This is to allow free circulation of electrolyte. This in- 
creases the internal resistance but very slightly, and the size of the 
cell for a given capacity. Following is a table of dimensions, weights

The clements of this battery consist of grids or plates of tead anti- 
moniated so as not to be acted on by the electrolyte, imbedded in and 
surrounded by a mass‘of active material. The plate or grid serves 
only as a conductor. It is rendered dense and’ of low resistance by

The details as to.constituents of active material are not given. The 
negative material is spongy lead and the positive lead peroxide. The 
plates are formed partly by Planté and partly by Faure processes. 

The active material after being pressed into a compact mass slir- 
rounding the grid, is enveloped by a sheath that retains the material 
in its proper position, and docs not allow it to fall away, This sheath 
consists of a framework of hard rubber or chemically prepared wood 
having a sheet of perforated hard rubber on cach side, These per- 
forations are t-16 inch in diameter and spaced 34 inch between centers, 

















FIG, 27.—DISCHARGE CURVE, REUTERDAHL CELL. 


The sheets of hard rubber are hejd against the frame by hard rubber 
bolts passing through holes in the sheets and framework. These 
bolts are of such length and so arranged that they serve to hold the 

-'sheets.against the frame, and to separate the composite plates from 
each other. Besides the bolts passing through the frame there are 
bolts passing through the plate itself, 

The purpose of these bolts is to hold the sheets of rubber at a 
fixed distance apart and thus insure the retention of the active ma- 
terial against the grid. 

The interior bolts are so staggered that a bolt from one clement 
does not abut against a bolt in the adjoining element but comes 
against the sheets of rubber surrounding that clement, so that with 
five bolts through cach there are 10 points of separation. The central 
bolts thus serve the double purpose of retaining the sheets in proper 
and definite retation to each other, as well as separating adjoining 
elements. The sheet rubber allows for expansion of the active ma- 
terial, as it combines flexibility and rigidity. 

The chief difference between this and other lead storage batteries 
consists in the retaining case and grid, which do not enter into the 
electrolytic action at all, The life of the element therefore docs not 
depend on the support, but on the active material only. The contain- 
ing jar is of hard rubber, with ribs on the bottom on which the ele- 
ments rest. All conductors are of antimonious lead cast under pres- 
sure, The capacity of the Reuterdahl 22-Ib. cell at a 3-hour discharge 
rate is given as follows: Amperes per pound, 1.5; watts per pound, 
2.85; ampere-hours per pound, 4.5; watt-hours per pound, 8.55. 


‘THE OSBURN BATTERY, 


This battery belongs to the pasted plate class, and at present is 
made exclusively for automobile work, The inventor, however, has 
attacked the problem of low cost of battery per mile of vehicle travel 
in an original and unusual way, 

The manufacturers contend that durability is only one of the fac- 
tors which make up the cost of maintenance and operation of an elec- 
tric vehicle, and that it resolves itself into the question of total cost 
of opcration per mile. In automobile work the questions of weight 
and cost of carrying this weight must be considered. Lead being the 
principal ingredient in a storage battery, and cach pound storing a 
given amount of energy, the life is shorter with a light weight bat- 
tery, but the battery also costs less. Therefore, it docs not appear 
economical to pay for and transport for an entire year a sufficient 
amount of lead for the succeeding year, 

Mr. Osburn, therefore, has set to work to produce a battery in 
which the elements will last from 6 to 12 months, and be light enough 
to reduce the total weight carricd to a minimum, and the cost low 
cnough to enable 2 complete replacement once or twice a year, and 

still keep the cost of battery per mile within a reasonable limit, 

This would certainly result in a satisfactory battery for the pur- 
chaser, as the initial investment is low, the maintenance not more 
than is usual with automobile batteries, and he would have a new 
battery at the beginning of the second year instead of one partly 


mere ares 


woes 


run down, With these ideas in view the Osburn battery was de- 
veloped. , 

In the construction of the grid lies the principal difference between 
it and the other varietics of pasted cells. These grids are made from 
pure lead of special manufacture, and are stamped in presses into a 
network of metal adapted to hold the active clement, and at the same, 
time to furnish a connection to all parts of it, ; 

The plate is formed from a thin shect of rolled lead. Rows of 
small square holes are punched into the sheet, diagonal cuts are then 
made from the corners of the holes, and the flap thus formed is 
turned at right angles to ‘the surface of the plate, forming a series 
of pockets for containing the active material, ' 

The thickness of the completed plate is equal to the sum of the 
thickness of the lead and the pockets formed by the portions turned 
at right angles. The opposite faces of the upturned portions form 
the side walls of adjacent pockets, while the greater portion of the 
edges are brought into contact with the active material, the only 
portions of the plate thus not in contact being the side edges of the 
sections. This insures a maximum amount of surface to the active 
material, therefore resulting in a maximum rate of discharge for a 
given weight. . 

The active material consists of precipitated Jead mixed with lead 
oxide and a small amount of some other chemical which the inventor 
does not at this time care to make public, The material is pasted 
into the grid and then subjected to pressure. The forming process 
is the same as that usual in pasted plates. It should be noticed that 
the applied material forms a continuous active surface, every part 
of the grid being covered. The grid is therefore protected from the 
action of the electrolyte, and disintegration avoided. 

The negative plates are made much thinner and lighter than the 
positive, as it has been found that the negatives may have their

read with interest the letter of Dr. Rocber in your‘. : 


in regard to concentration changes in the pores of 


vs ¢{the plates of the Edison accumulator, and also your suggestive edi- 


torial comment on the letter, 


Undoubtedly such changes take place, Whenever a current passes 
{through an “electro-chemical field” from anode to cathode, as is 


ot well known, there is a concentration of the kations at the cathode 


and anions at the anode, This can be explained by the ionic theory 
on the Sround that the ions bear electric charges and ‘the electro- 
static attraction due to the Potential drop causes them to move 
| slowly through the electrolyte. This electro-chemical movement is 
comparable to the falling of fine particles through a retarding me- 
dium under the influence of gravity, For example, there is 2 complete 
analogy between the mechanical falling of precipitated chalk through 
water and the electro-chemical transport of copper from anode to 
cathode in electro-plating. The friction of the particles is so great 
that they move not with accelerated motion, but ata constant velocity, 
Granted, however, that there are such concentration changes and 
that the caustic potash solution becomes more concentrated at the 
nickel superoxide plate and more dilute at the iron plate, such changes 
would have small effect on the voltages of the cell, 
The cm, £, of the nickel superoxide plate against hydrogen would 
be at different concentrations, 


Cy ey = 2258 log u 


where Piand pz are the aqueous tensions of the two caustic solutions. 
A similar formula comes in for the positive plate. This would show 
that the change from a 20 per cent solution to a 1 per cent solution 
would make very slight difference in the voltage of the cell (not much 
over 0,03 volt), and not at all sufficient to account for the steady drop 
of voltage of the new accumulator, In the lead cell we have, how- 
ever, for acid of density 1.496 a voltage of 2.29, and for acid of den- 
sity 1.028 a voltage of 1,83—a difference of 0.46 volt, 

So this drop in voltage due to concentration changes in the Edison 
cell is not at all comparable to the change of ‘voltage due to concen- 
tration of acid in the lead accumulator, where a more complicated 
formula, duc to the fact that both the dissolved substance and the 
solvent take part in the electro-chemical reaction, 

(Pb Os-+ Pb+- 2 H:— SO. = 2 Ph S0.-+- 2H, 0) 
must be deduced, We also see from the above equation that the 
changes in concentration in the pores of the plates are much more 
important with the lead cell than with the new Edison accumulator, 
as well as producing more effect on the voltage. 

The change in the resistance of the Edison electrolyte in the pores 
Of the plate is negative; that is, the resistance of the positive increases 


more than the negative decreases. This will account for some of the 
fall in the discharge, but not for all. “ 
The drop is probably due in great part to the fact that at first. the | 
current acts electro-chemically on the particles of oxide in the best | 
electrical contact with the plate, and at the end of discharge must ! 
find as its depolarizer, oxide electrically remote from the plate. A | 
corresponding drop will be found also at the iron plate. The most 
important consideration is the resistance of the briquettes as affected 
by changes of the discharge and charge as well as by changes of the 
resistance of the electrolyte. Certain compounds as NiS, FeS, PbS, 
FeO, PbO:, and CuO act as fairly good conductors of the first class. 
In the Edison cell, the oxides must be conductors to some extent. 
The probable reason for the so-called electro-chemical “passivity” 
is the fact that the products of the electrolysis are insulators; and so 
protect inside layers. The strength of the lead cells is in the Pb and |. : 
. PbO; as metallic conductors, while conversely its weakness lies in 
the lead sulphate. The strength of the new Edison accumlator partly 
lies, no doubt, in the fact that the products of the electro-chemical 
action conduct, but largely also in the skillful combination of me- |: ° 
chanicat and electro-chemical treatment in the manufacture of the |’ 
plates by the inventor. °" ” Wootsty McA. Jonnson,

In France, the last two years have been . : '

battery is reversed after discharging. 
Magnesium standing higher in the elec- 
trie series of active metals than zine, ob- 
viously can not produce any action.on tho 
latter, Therefore, if an electric action 
did occur in the battery between the met- 
als, it would necessarily affect the mag- 
nesium and not the zine. However, in 
practice the magnesium is not attacked, 
but remains absolutely neutral. There is 
no local action between the two metals, 
and neither hydrogen nor zine hydroxide 
is formed, as was the case with batteries 
of the type heretofore made employing 
‘zine as the active material in an alkaline 
solution, With this battery the zine’ is 
plated out ofthe solution upon the mag- 
nesium support in a dense and adherent 
form, and even with a large volume of 
current very considerable amounts of zinc 
can be thus deposited before the surface 


‘assumes a non-coherent character. He 


can not positively explain why the mag- 
nesium is not attacked and why local ac- 
tion does not take place thereon, a8 ordi- 
‘narily magnesium is much more oxidiz- 
able than zinc. He believes, however, a3 


’ the result of numerous experiments, that 


the phenomenon is satisfactorily ex- 
plained by the supposition that the mag- 
nesium is coated with an extremely thin 
layer of oxide, insoluble in the liquid, 
and that the zine is deposited upon the 
film of oxide and not upon the metal itself. 
Tf this supposition is correct, then the 
electric charges of the zinc ions apparently 
pass to the metal through this Jayer. In 
this improved battery he prefers to use, 
copper oxide as the negative clement. 
Finely divided copper is preferred, which 
is first moulded in form, then subjected 
to heat, so as to convert it into the black 
oxide, after which it is finally reduced to 
metallic: copper by electrolytic action, so 
that in charging it will be reoxidized by 
.the current to the red oxide (Cu,0). 
The copper oxide so treated in the form 
of blocks or cakes of the desired size is 
preferably supported by perforated re- 
ceptacles attached to nickel or nickel- 
plated plates. The solution employed is 
about a twenty per cent solution of 
caustic soda, to which zinc hydroxide .is 
added until it is nearly saturated. The 
_™Magnesium supports are in the form. of 


than if the- plates are imperforate, in 
which latter case.a very much greater de- 
posit takes place at the edges thereof than 
at any other point. The negative ele- 
ments are formed of nickel or nickel- 
plated plates, carrying perforated nickel 
or nickel-plated pockets or receptacles, se- 
cured ‘thereto, the plates’ being formed

SronacE Battery, 


with lugs by which they may be assem- 
bled and electrically connected in the 
usual way, When the cell is in a neutral 
or fully discharged condition, the copper 
oxide plates or blocks will be reduced to 
the metallic state and the zine will be in 
solution. In charging, the copper is oxi- 
dized and converted to the red oxide 
(Cu,0), while the zinc is deposited clec- 
trically upon the magnesium electrodes. 
The charging is continued: until about 
seventy-five per cent of the zine in the so- 
‘lution is thus deposited, whereupon the 
ecll is ready to be discharged. In dis- 
charging, obviously, the reverse operations 
* take place, the copper oxide being con- 
verted to the metallic state and the zinc 
going back into the solution. The volt- 
age of this battery is 0.67 volt, In dis- 
charging it will be found that a point is 
reached where the voltage falls consider- 
ably, due to. the approach to exhaustion 
of the oxygen in the copper, and the dis- 
charge should not be permitted to take 
place materially beyond that point. The 


positive and negative elements are prop- . 


serly connected and are supported in a 
suitable enclosing jar, hermetically sealed 
from the air, the jar being provided with 
a vent for the escape of any gas generated 
therein. In another buttery, patented at the 


is not considered as desirable for use as 
nickel owing to its greater cost and to the 
fact that it is slightly soluble in an alka- 
line electrolyte. The electrode for sup- 
porting the depolarizing material is made, 


preferably, of sheet stecl carefully nickel- * 


plated so as to be unattacked by the al- 
kaline solution, and provided with pock- 
ets or receptacles having perforated walls 
and within which the depolarizing 1a0- 
terial is maintained under pressure, so as 
to be at all times in good electrical con- 
tact with such walls, said pockets or re- 
eeptacles being made of very thin nickel- 
plated sheet steel high in carbon, so as to 


be . sufficiently elastic to accommodate . 


changes in bulk of the active material. 
Herr Arthur Lehmann, residing in Ber- 


-lin, Germany, has also obtained a patent 


in this country on a new process for pre- 
paring secondary battery plates, the object 
of the invention being to shorten the time 
required for the production of the plates. 
“The lead electrodes coming from -the 
founding machine are made to show a 
chemically pure metallic surface, for which 
purpose brushes or a jet of sand-blast are 
used. These plates are then conveyed into 
a bath containing a solution of an organic 
acid. The acid can be palmitic acid, 
stearic acid, oxalic acid, lactic acid, etc., 
or any one of the fatty acids. In this bath 
the electrodes are exposed to an electric 
eurrent for a certain Jength of time. In 
this bath, under the action of the elec- 
trie current, the plates are rendered 
more receptive and the surface is in- 
creased similar to ribbed plates.’ The re- 
actions taking place are for the applica- 
tion of oxalic noid (C,0,H,). The acid 
decomposes under the influence of the 
electrical current, and 0,0,combines with 
Pb to 0,0,Pb (oxalate of lead), When 
carbonate of sodinm is added to the 
oxalic acid, there is formed first from 
0,0,H,; and Na,00, 0,0,Na,00,H,0. 
From the oxalate of sodium 0,0,Na, there 
takes place another separation into Nay 
and 0,0,, the latter combining with Pb. 
Tt hag been found that the lead electrodes 
are attacked more intensely in the bath 
containing an organic acid if the acid solu- 
tion in the sath is neutralized or made 
alkaline by the addition of carbonate of 
sodium. After. the. current hos been

us the fundamental basis for making a

passed through the solution the alkaline 
solution becomes acid, and it is thought 
that the organic acid employed is more 
effective in the nascent state. From the 
deep coloring of the positive plates can be 
judged whether the plates have beei ‘at- 
tacked sufficiently. In that case the plates 
are removed, washed in running water, 
and then hung up in a bath containing lye 
of caustic soda, After the plates have 
been exposed to the lye of cauatic soda for 
a certain time they are again washed in 
running water and dried, so that nothing 
remains of the organic acid used to attack 
the plate and to make it a conductor. For 
the further formation of accumulators aul- 
phurie acid can be used. In the sulphuric 
acid the plates are then exposed to the clec- 
tric current for about fifty hours, and they 
can then be considered ready for use.” 
Another patent has just been issued to 
Mr. ‘Nikola ‘Tesla, the present invention 
relating to apparatus for the utilization 
of what the inventor calls radiant energy, 
such as the sun’s rays and the like. It is 
well known that certain radiations—such 
as those of ‘ultra-violet light, cathodic, 
Reentgen rays, or the like—possess the 
property of charging and discharging con- 
ductors of electricity, the discharge being 
particularly noticeable when the conductor 
upon which the rays impinge is negatively 
electrified. ‘These radiations are generally 
considered to be ether vibrations of ex- 
tremely small wave-lengths, and in ex- 
planation of the phenomena noted it has 
been assumed by some authorities that 
they ionize or render conducting the at- 
mosphere through which they are propa- 
gated. Mr, ‘Lesla’s experiments and ob- 
servations, however, have led -him to con- 
clusions more in accord with the theory 
heretofore advanced by him that sources 
of such radiant energy throw off with great 
velocity minute particles of matter which 
are strongly electrified, and therefore 
capable-of charging an electrical con- 
ductor, or, even if not so, may at any rate 
discharge an electrified conductor, either 
by carrying off bodily its charge or other- 
wise. ‘The present invention is based upon 
a discovery, which he claims to have made, 
that when rays or radiations ‘of the above 
kind are permitted to fall upon an in- 
sulated conducting body connected to one 
of the terminals of a condenser while the 
other terminal of the same is made by 
independent means to receive or to carry 
away electricity, a current flows into the 
condenser’so long as the insulated body 
is exposed to the rays, and under the condi- 
tions hereinafter specified an indefinite 
accumulation of electrical energy in the 


cénilenser takes‘place. This enbrgy, after"

a suitable time interval, ‘during which the 
rays are allowed to act, may manifest it- 
self in a powerful discharge, which -may 
be utilized for the operation or control 
of mechanical’ or electrical devices or 
rendered useful in many other ways. -In 
applying this discovery Mr, Tesla provides 
a condenser, preferably of considerable 
electrostatic capacity, and connects one of 
its terminals to an insulated metal plate 
or other conducting body exposed:to the 
rays or streams of radiant matter. It is 
very important, particularly in view of 
the fact that electrical energy is generally 
supplied at a very: slow rate to the con- 
denser, to construct the same with the 
greatest care. He uses, by preference, the 
est quality of mica as dielectric, taking 
every possible precaution in insulating the 





armatures, so thattheinstrument may with- 
stand great electrical pressures without 
leaking, and may leave no perceptible elec- 
trification when discharging instantancous- 
ly. Obviously, the above precautions 
should be more rigorously observed, the 
slower the rate of charging and the small- 
er the time interval during which the en- 
ergy is allowed to accumulate in the con- 
denser. The insulated plate or conduct- 
ing body should present as large a surface 
as practicable to the rays or streams of 
matter, he having ‘ascertained thet the 
amount of energy conveyed to it per unit 
of time is under otherwise identical con- 
ditions proportionate to the area exposed, 
or nearly so. Furthermore, the surface 
should be clean and preferably highly pol- 
ished or amalgamated. ‘The second termi- 
nal or armature of the condenser may be 
connected to one of the poles of a battery 
or other source of clectricity or to any con- 
ducting body or object whatever of such 
properties, or so conditioned that by its 
means electricity of the required sign will 
be supplicd to the terminal.’ A simple 
away of supplying positive or negative clec- 
tricity to the terminal is to connect the 


_ same either to an insulated conductor sup- 


ported at some height in the atmosphere 
or to a grounded conductor, the former, 
as"is ‘well Xnown; ‘furnishing positive ‘and

‘Or supposed streams of matter generally 
convey a positive charge to the first con- 
denser terminal, which is connected to the 
plato or conductor above mentioned, the 
second terminal of the’ condenser ia usual. 
ly conneeted to tho ground, this being tlio 
most convenient way of obtaining negative 
clectricity, dispensing with the necessity 
of providing an artificial source. ‘In order 
to utilize for any useful purpose ‘the en: 
ergy accumulated in the condenser, thero 
is furthermore connected to the terniinals 
of the same a’ circuit including an instin- 
mient or apparatus which it is ‘desired to 
operate and another instrumézit or device 
for alternately closing and opening the 
circuit. ‘This Jitter may be any form of 
circuit controller, with fixed or movable 
parta or electrodes, which may be actuated 
either by the stored energy or by independ.

fully understood from the accompanying 
drawings, in which Fig. 1 is a diagram 
showing the general arrangement of ap- 
paratus as usually employed. Trig. 2 isa

tail typical forms of the devices or ele.

found that when the radiations of the sun

This phenomenon is best explained as

continuously an electrical change to the

{ 











of apparatus which may be used in carry- 
ing out the discovery. In this figure, 
which in the general arrangement of the 
clements is identical to Fig. 1, the de 
vice d is shown as composed of two very 
thin condueting plates ¢ ¢’, placed in close 
proximity and very mobile, either by rea- 
son of extreme flexibility or owing to the 
character of their support. To improve 
their action they should be enclosed in a 
receptacle from which the air may be ex- 
hausted. The plates ¢ ¢' are connected in 
series with a working circuit, including a 
suitable receiver, which in this case is 
shown as consisting of an electromagnet 
M, a removable armature a, a retractile 
spring 8, and a ratchet-wheel w, provided 
with a spring pawl +, which is pivoted to 
armature a, ns illustrated. When the ra- 
diations of the sun or other radiant source 
fall upon plate P, a current flows into the 
condenser, as above explained, until the 
potential therein rises sufficiently to at- 
tract and bring into contact the two plates 
i? and thereby close the circuit connected 
to the two condenser terminals. This per- 
mits a flow of current which energizes the 
magnet M, causing it to draw down the 
armature a and impart a partial rotation 
to the rntchet-wheel w. As the current 
ceases the armature is retracted by the 
spring b, without, however, moving the 
; Wheel w. With the stoppage of the current 
the plates £ ¢’ cease to be attracted and 
separate, thus restoring the circuit to its 
original condition, — 

Mr. Noble Jones, a resident of Spar-

on a fuse cutout which he claims will 
ordinarily prevent the areing when the 
fuse is melted and, in any event, will con- 
fine the fire due to arcing should it occur 
to the fuse box or block. A fuse box is 
made in the ordinary manner, comprising 
a porcelain body having binding-posts, to 
which the line wires are attached, a pair 
of the posts carry clamping screws to 
which the ends of the fuse wires are se- 
cured, Located contiguous to, but insu- 
Inted from, the other posts are other 
clamping screws to. which the opposite 
ends of the Tuse wi te secured. The

that the, magnets are in series with the

out or extinguished by the action of the 
magnet arranged directly beneath it. Thus 
all danger of fire from this cause is re-

The Edison Storage Battery, 





Ever since Dr. A. &, Kennelly read his admirable paper last May 
before the American Institute of Electrical Engineers, on the Edison 
iron-nickel storage battery, the keenest interest in the subject has 
been taken not alone by the electrical profession but by those en- 
gaged in many other fields of industrial application, notably that of 
automobilism. This interest has again been stimulated by the loan 
exhibit at the recent automobile show in Madison Square Garden 
of a complete cell of the battery. The cell was y2 inches high, 2 
inches thick, 5 inches wide,-and weighed 7% Ibs, giving 120 watt- 
hours, or 46 lbs, per horse-power-hour. The cell was also shown in 
its detail parts, and the steel plates excited much comment and sur- 
prise, being in sharp contrast to the familiar ones of Jead. 

The publicity given to Mr. Edison’s work has led people to ex- 
pect to buy the battery even now in the open market, and the dis- 
appointment* expressed jn many quarters is not fair to the dis- 
tinguished inventor, The Kennelly paper was presented last spring 
against Mr. Edison's desire, but in compliance with an universal re- 


quest that he would “show his hand” and tell the public what it was | 


that he was working at jn storage batteries. In the interval, Mr. 
Edison, who has always {ogked upon the Institute as the proper chan- 


nel for these important communications,.has maintained an absolute | 


silence, but it would be the wildest mistake to suppose that he had 
also been idle. One thing can always be predicated about Mr. Edi- 
son, viz., that whether he talks or abstains from speech he is always 
hard at work, Indeed, although he has now reached the term of 
life where men of great achievement may rest on'their laurels in dig- 
nified ease, it may be questioned whether he hag ever followed up 
anything with more unrelenting zeal and enthusiasm than he has 
displayed in the unremitted work given to this his latest and, in some 
respects, his greatest invention. 

Last June note was made in these pages of the formation of the 
Edison Storage Battery Company, with a capital of $1,000,000, and 
since then reference has been made to the establishment of a fac- 
tory at Glen Ridge, N, J,, not far from the Edison Laboratory, for 
the production of the battery. This means a good deal more than 
the superficial signs would indicate. At this present moment, the 
Glen Ridge factory is so far advanced that the manufacture of bat- 
teries will begin with the new year, and deliveries should come 
early in the spring. The inquiries and orders ate such as to ensure 
that there will be no accumulation of the output, although provision 
has been made for an {nitial production of 100 horse-power capacity 

~ daily, although this Mr, Edison looks: upon only as.an entering 
wedge. The factory was originally a plant for the manufacture of 
fine jewelry, and some of its machinery is still available, but it has 
_ been thoroughly renovated and modernized, and a large amount of 
new imachinery, tools, ec, has been put in. The main building is 
three stories, in addition to which there'are large wings comprising 
machine shop, drying rooms, nickel-plating plant, ete. Dynamos, 
engines, boilers, etc, are already in place, and the machine shop 
has a fine equipment, including some special apparatus. 

A mile or two away—the distance, depending on which road you 
take—is the Edison chemical plant at Silver Lake, Here the well- 
known Edison-Lalande battery has been made for some years past, 

‘and now the chemical plant necessary for the new storage battery 
has been added. Several aeres of fand have also been acquired, the 
site being an ideal one for manufacturing uses, and the plan being

devoted to the water digtiffation ‘plant. Another will be devoted to 
‘the. treatment of the nickel, and. is already cquipped with the neces- 
sary, vats, etc. A third targe shop is occupied by the plant for pre- 
paring the iron oxide ang the graphite. All embody many novelties 
i, construction and equipment, and show that not'only has'a master 








mind been actively employed on the various problems, but that no 
small amount of executive ability has been given to the task of 
Preparation. Indeed, at the present time, the attention is incessant 
that is being given to the subject by Mr. Edison's staff, especially 
ae W. S. Mallory, W. E, Gilmore, F, R, Upton and J.-M, 

ill, 

When interviewed on the subject last week, Mr. Edison expressed 
himself with the firmest conviction as to the real success he has at- 




































operation, he pointed out that by far the largest Percentage of cost 
lay in the, element of depreciation, Under the most rigorous tests,~ 







as‘shown by ‘the records, appears to have dwindled to an inappre- 
ciable minimum. These tests now extend virtually over a couple 
of years, but are still being persisted in, with the object of determin- 
ing any weakness, wherever it may lurk, As to the cost of the cell, Mr. 
Edison proposes to market it somewhere around the present cost of 
lead batteries, So far as can be ascertained, the type of cell noted 
above is the standard, such as would be used, for example, in auto- 
mobile work. But it would appear that for Stationary work far 
larger grids can be used; indeed, there is said to.be no valid reason |: 
why they should not be 10 ft. high, or even as big as the side of a 
house, For separators between the plates, several successful types 
have been used, some of which are quite original, As a matter of}, 
fact the cell is so full of plates there is little room provided for either: 
separators or the potash solution; but with plates so thin—one-tenth}

The Debt of Electrical Engineering to C. E, L. 
Brown—IV, 
By B.A, Benrenp,

THE LAUFFEN Type GENERATOR, 


fs bass first and most needful step was to make a generator that 
could be used equally well for single-phase and for polyphase 
currents. Thus Mr, Brown invented and designed the “Lauf- 
fen Type” represented in Figs, 18 and 19. 

In his Frankfort lecture of Feb, 9, 1891, Mr, Brown thus describes 
the main principles that guided him in Creating this construction, 
“The generator must be an alternating-current dynamo, whose ten- 
sion we will choose as low as Possible, for thus such a dynamo can 
be made a machine in the fullest sense of the word, This will be 
clear if I adduce as illustration the winding of the armatures of the 
dynamos designed for supplying three-phase currents to the Ocrlikon 
Tool & Engine Works, which consists of copper bars 30 mm. thick,

the magnet is presented to the arc, As soon as the arc is divided into 
the two wings, the instruments read the average current flowing dn 
each circuit, and also indicate that these two portions flow in opposite 


directions. fe ee

when there is zero current in the other. The current curve, however,

siderable experience, that a negative plate can be made light and 

yet ast during: four of five years of constant service. Since the 

positive electrode is the weak point of the cell, I shall concern my- 

self more particularly with it ae 7 

In dischatging a lead storage ‘cell, lead ssulplfate is formed on 
. either plate! This sulphate being insoluble remains in its position 
and there is‘thus formedja mixture of lead peroxide'and lead sul- 
phate on the positive electrode, and spongy lead and lead sulphate 
on the negative. As the proportion of ‘sulphate increases, the con- 
-~ ductivity of the mixture decreases, In practice the proportion of 
the sulphate is not allowed to increase to more than 50 per cent., 
as at this point the. electromotive force of the cell: falls<(and even 
before ‘this point is reached), and further sulphation takes place 
rapidly if the cell is not at once recharged, . 
. It is held ‘by some that this mixture js in reality a complex com- 
pound; that thé Jead peroxide of a charged cell is not as represented 
by the simple formula PbO,, but is an allotropic form in which many 
simple molecules are combined into the complex one (PbOs).x, where 
+ is an unknown number but assumed to be 50 for mere convenience, 
Then the discharge of the positive electrode will be represented by a 
series of changes in the molecules, as follows: (PbOs)0, (PbOs)a" 
PSO. (PbOs)a° (PLSO)s, . . .. to approximately. (PbOs)2.° 
(PbSO.)u, when the electrode has practically reached its discharge 
limit. Each molecule contains some lead peroxide throughout the 
discharge and keeps the mass conductive, The molecule becomes 
less stable as the percentage of peroxide decreases, and when the point 
represented ‘by (PbOs)3s° (PbSO.)s is approximately reached, it 
readily breaks up with the formation of ordinary lead sulphate and 
simple molecules of lead peroxide, thus accounting for the rapid sul- 
phation which is apt to take place if 4 cell is allowed to remain long 
uncharged, This structtire of the molecule also accounts for the case 
with which the discharged plate is’ reconverted to the peroxide con- 
dition, it being gerierally held:that pure silphate of lead is very slowly 
converted to the peroxide electrolytically, and only with a relatively 
large expenditure of-energy,  - . 

This theory of thé complex tature of the lead peroxide molecule 
was brought forward by Wade in a paper read before the British 
Institution of Electrical Engineers, 

Theory is a thing to explain facts, . Whatever the theory held, the 
fact remains that sulphate of lead does form rapidly if the cell is 
allowed to stand: uncharged, and also forms under other conditions 
which are not well understood. Although.sulphation can be controlled 
to a certain extent by exercising great care, it is still a serious ‘draw- 
back to the use of lead in batteries, and is in a large measure respon- 
sible for the rapid deterioration of the plates, 2 

Another cause for deterioration is the.lack of porosity in the active 
mass. The plate cannot absorb sufficient :acid for its discharge, and 


50 must depend upon diffusion, A heavy discharge will exhaust the - 


acid in the interior of the active mass, and, as was shown by Glad- 
mh and Tribe, the normal. reactions do not take place in very dilute 
acid, ~ . ; : , 

A rapid charge may loosen particles of the active material by the 
too rapid evolution of gas. This is known as scaling,” 

In pasted plates the peroxide mass softens when subjected to severe 
service in'an automobile, and tends to wash away from the grid. 
This result takes place in a very short time if sediment is allowed 
to accumulate in the bottom of the cell until it touches the lower 
edges of the plates and thus causes a short-circuit, This sediment, 
consisting of lead sulphate, is continually forming and necessitates 
the frequent washing of the battery to avoid harm to the plates, 

In order to preverit the falling away of active material, due to the 
softening of the mass and to dislodgment by escaping gas, and to 
Prevent sediment from falling to the bottom of the cell, some battery 

makers ‘wrap the plates with some porous substance, as specially 
treated cellulose, glass, wool, etc. I do not know to ‘what extent this 
method is alleviating the trouble, but in my opinion it cannot stop 
the formation of ‘sediment, which I believe is due to the following 
Causes: * ¢ 
: Lead sulphate is soluble in concentrated sulphuric acid, is prac- 
tically insoluble in dilute acid, and is again slightly soluble in pure 
water, In charging a ‘cell at a fairly rapid rate, sulphuric acid is liber- 
ated in the Pores of the active masses faster than’ it can diffuse out. 
Therefore the interior of the plates must contain fairly concentrated 
acid, in which’ lead: sulphate is slightly soluble. This strong acid 
carrying lead sulphate, slowly diffusés out of ‘the plates and is there 
diluted by the. weaker acid. The sulphate being less soluble in ‘the

weaker acid, is precipitated and settles to the bottom of the cell, Th 
action would take place througli the porous envelope and so form’a 
sediment the same as without it, ” 


The way to prevent this action would seem from the foregoing -to \ 


be by preparing the plates with greater porosity,’ so that the acid could 
diffuse more rapidly, ‘and so avoid. great changes in density of the 
electrolyte, or by preventing the, formation ‘of the white, sulphate, as- 
suming Wade's theory to be correct; preferably by both methods 
together, “etn Wee ; 

Mr. G. H. Robertson thinks that the formation of sulphate might 
be checked by adding somé stibstance to the electrolyte that will pre- 
vent the formation of oxidized bodies init, and which at the same 
time wifl not injure the plates. eee 

ZINC-COPPER OXIDE CELL, 


This cell, which uses an alkaline hydroxide electrolyte, possesses 
certain advantages over the lead cell, but also introduces new diffi- 
culties, which have rendered it less useful than the lead type. In the 
alkaljge cell there is no'such thing as sulphating and buckling, and 
no hatm is done to the plates even if charge does not immediately 
follow the gischarge, inlphin eke coisa 

The zinc negative, however, is liable to local action, and great diffi- 
cully is experienced in’ plating the zinc in compact form available for 
the discharge. To charge the cell, the temperature should be about 
54° Centrigrade, and the charg : 
duce the best results. These ‘conditi cannot always be realized 
in practice, and since the life‘of thie‘ce}f'is' rather short and its applica- 
tion ‘somewhat, limited, owing’ to the?comparatively short time that 
it will retain its charge, this' type hi been able to fulfil the exe 
pectations of its. promoters, | °° : :

Tt scems likely that the reaction of dischargéis in many respects 
analogous to that of lead peroxide, and that the capacity is only 
about half of the theoretical.“ In-normal dischargé, I believe that 
the lowest oxide formed is the sesquioxide NisOs (sometimes called 
peroxide), but under certain conditions the nickelous oxide (NiO) 
might be formed, and would present difficulties similar to those due 
to the formation of lead sulphate in the lead cell were it not' for the - 
fact, that the oxide is insoluble, so that it remains in place.and is 
slowly brought back to the Proper condition, ak BPs 

Overcharging does not harm the plates, because nickel. is hot

not be present, as nickel is more readily attacked in such ‘solutions, !

publications, technical journals, and other printed sources. The articles and 
interviews pertain to a variety of subjects, including the development and 
promotion of Edison's inventions and the personal affairs of Edison and his 
family. Included are clippings relating to the personnel, activities, and legal 
affairs of Edison's various companies, as well as articles about phonographs, 
phonograph records, motion pictures, and storage batteries. There are also 
clippings concerning Edison’s cement plant at Stewartsville, New Jersey; his 
plans for a poured concrete house; and his efforts to develop a combined 
phonograph and motion picture machine and a process for the exploitation of 
dry placer gold claims. Also included are items relating to the suicide of 
Edison's secretary, John F. Randolph; a kidnaping threat against his daughter, 
Madeleine; the marriages of his sons, Thomas A. Edison, Jr., and William 
Leslie Edison; and the travel, property holdings, and recreational activities of 
Edison and his family. Some of the articles bearing an Edison by-line were 
probably prepared for him by his associates, and some are the result of 
interviews with journalists at the West Orange laboratory. 


The clippings are arranged in rough chronological order within each year. 
In many cases, several small newspaper clippings of differing dates are taped 
onto the same sheet of paper. Some sheets also contain archival notations 
referring to the Document File folder in which the clipping was at one time 
filed. Other archival inscriptions can be found throughout. Because of their 
deteriorating condition, all of the newspaper clippings at the Edison National 
Historic Site are being photocopied, and the originals discarded. The clippings 
presented in this edition constitute a mix of originals and photocopies. Some 
may be difficult to read because of the discolored paper. There are also a few 
negative photostats of journal articles that may present legibility problems. 


Less than 20 percent of the clippings for 1899-1910 have been 
selected. Many of the items not selected are based on wire service reports 
that were widely circulated and carried in numerous papers. In such cases, 
one version of the report has been selected as a sample.

Objects to His Name Belng Used to Furt 
Questionable Schemes--Arrests in “ 
Jacksonville at is equoat 


The arrest of the persons calling them- 
selves “Baron and Baroness Debara’ at} 
Jacksonville, Fla, Tuesday, as told inj 
the NEWS yesterday, was made at the In- ; 
stance of Thomas «A, Edison, through hit 
counsel, Howard W. Hayes, of this elty, 
The action was taken in furtherance of 2B i 
new palley adopted by Mr. Edizon regard. i 
ing the use of his name by others in pusi- | 
ness, ¢ “h 
For yearg Mr, Edison hag been bothered { 
by the actions of irresponsible persons 
who organized Edison “companies or 
established themselves as “agents” of the © 
inventor without authority, Jn muny cases 
where people were duped by the alleged 
agents they would write to Mr, Edison for 
redress. A few months age Mr, Ed{son 
decided to put a stop to thé practice, ft 
was about this time that word reached the 
inventor from the Edison Electric Light 
Company of Chicago, that a man in that 
eity, calling himself George B, Henschel, 
was selling territorial rights for the’ sale 
of phonographs, Later u letter was re 
celved from the British Consul tn} Chi- 
cago that Henschel! had sold certalii” ai- 
leged rights to peopte In Englund, . "2", 

Mr, Edison concluded to put his nev 
policy into effect and the matter we 
placed in Mr, Hayes’s hands, It was learu 
ed that Mr, Hengchell claimed to have at 
office at 118 Dearborn street, Chicago. 
Monk & Elliott, lawyers, of the Wind) 
City, were requested to make an investi- 
gation, end word was sent back that Hen- 
schell had no office at the address given. 
Then charges were preferred against the 
man, and United States District-Attorney 
John C. Black, of Chicago, was requested 
to act. © 

When the Federal authorities were put 
on his trafl the man disappeared. About 
the same time a woman, who called her- 
self Eva Wilson, and acted as a clerk for 
Henschell, also left Chicngo. Henschell 
left orders to have lis mail sent to Green- 
wich, Conn, He never showed up at that 
place, but It fs sald that the couple were 
traced to St. Augustine, Fla., by the pos- 
tal authorities, When the Baron and Bar- 
oness Debara were arrested, William HH.

THOMAS A. EDISON 


We wailed for tlm in the Ibrary of his 
magnificent laboratory at West Orange, New 
Jersey—walted nervously, for we were not 
there by invitation, but as Intruders, and 
Mable to arrest for all we Knew to the con- 
trary. No one had replied when we pressed 
the button at the gate of the high picket 
fence, Intended to protect the busy 
“Wizard” from a too admiring or too curl- 
oug public. We represented beth of these 
classes, also another, celebrated for its 
“nerve,” and we had come too far and 
were too much in earnest to allow a little 
thing Mke a plcket fence to keep us out. 
Even barbed wire could not have done It 
with Thomas A. Edison on the other side. 
We were quite willing to risk Jeaving sam- 
ples of our tallor-nade gowns on the plekets 
just for the satisfaction of getting Inalde 
the ningle enclosure, even though we were 
thrown out bodfly the next minute, 

But It didn't come to that, “Heaven helps 
those who help themselves," and this thie 
henven sent a small boy, whom we 
“poosted" over the fence, aud who wnlocked 
the gate from: the inslde, showed us the way 
into the Ilbrary and then ran for his Ife, . 

Waylaying the first employe that passed, 


we wheedled him Into carrying a card with |. 


A more or less “tender message written 
upon It, to Mr. Edison, and the Kindly word 
came-back, delivered by the same employe, 
now In a broad grin, that Mr." Edison was 
about to leave for New York, but would see 
ug before leaving, 





————— 
Lho Wizard's Attractiva Smile. 


Soon as the attendant’s back was turned 
we fell upon cach other's necks In a dellrlous 
embrace over what we considered our great 
luck; then we attempted to compose our 
selves In order to mect thls great man with 
tt dignity forelgu to pleket fence cllmbing, 
and akin to what we Imagined his own would 
de Ike, But how unlike the real Edlson was 
the Edfson of our fancy, and how much moro 
charming! Inatend of 1 tustldlously dressed 
“hoss" with severe countenance, upon thls 
ocenston puckered with displeasure over our 
intrusion and Intended to show us he had 
ho thme for women whe could no moro un. 
derstand his work than a couple of geese 
could; Snstend of this style and manner he 
came In sintiing, his well-worn pepper and 
salt ault as dirty as that of any workman 
on the place, and hokling one chemleally- 
discolored hand up ‘to the ear mude deat 
by the cruel blow of a railrond conductor 
who had no paticneo with the newsboy 
Tom Edison who was forever making ex. 
perlments with chemicals even on the traln, 
and who tuls thne had caused an explosion, 

But here he stood before us, the same 
newsboy who got his ears hoxed; afterward i 
the poor young telegraph operator wander. 
Ing from place to place, making a: record 
as a Wghtnuing operator, and atways hunting 
for the cheapest restaurants, ‘The same who 
Inter Invented the famous stock-ticker und 
who dldn't know what to do with the $40,- 
000 he got for the patent; the same wizard 
at whose magle touch were to spring [nto 
exfatence those marvels of Inventlon—the 
quadruplex telegraph, the carbon infero- 
phone, the Incandescent light, the phono- 
graph, ete, ete. Here was’ before us the 
poor boy, homeless, moneyless and unknown 
no longer; but a man now, 2 milonatre, the 
finest house In West Orange for a home, 
countless friends and honors of every kind 
continually being thruat upon him; © mem- 
ber of the Legion of Honor now, and during | 
the French Exposition af 1889 the orchestra 
played the Amertenn national anthem when 
he entered the Grand Opera House In Paris, 
and this-we know is a compllinent which Is 
paid only on the entrance of kings, 


Quite an Alffablo Irost. 


We found {t all hard to reatire~a falry 
tale in fact—now that we were In his pres- 
ence and he stood shaking his head In mock 
gravity over the situation, his kindly eyes 
full of a humorous twinkle and his rea, 
white and blue hand held back of his car 
to catch our denial of having climbed over 
the fence, which he Inughingly sald he 
wouldn't put past us, But it was all right, 
and he wag sorry we had any trouble to get 
in; sorry, too, he had to go to New York to 
bury one of his workmen; safd he atways 
made it a polnt to gee hia “boys” lald away; 
had just returned from burylng his father-In- 
Jaw, left Mrs. Edison with her people or 
he would take us over to “Glenmont" (the 
name of hls home), but hoped we would en. 
Joy our vist to the laboratory; he would 
send Mr, Hatlentine, hls right bower, to con- 
duct us over the building, and we had his 
permission to carry away anything loose 
thit we wanted, ete, 

But we only wanted to carry away his 
photograph and his autograph, and these he 
gave us himself, writing bla namo Jn the 
pretty way we have always scen it, and 
without the least nervousness, though ho 
was In a desperate hurry, 

The fine dock-talled bay horse and top 
Dugey stool at the door, ao throwlng himself 
into a dlsreputadle looking gray ulster that 
didn't seem to fit hin anywhere, he jumped 
Into the vehicle and was drlyen out of the 
Inboratory grounds, and we were taken In 
charge by Mr. Batlentine, a genlal Scotch- 
man, who had been some years with Mr 
Edlson, and who seemed full of veneration 
for the “Wlzard," though this we discovered 
was the genera! feellng among the men, 

Whilo waiting for Mr. Ballentine’ to “nt. 
tend to some Ilttle matter’ before he contd 
show us around we had time to examine 
thoroughly the pretty Ibrary where Mr. 
Edigon recelyes, his callers: and ‘where he 
must do lis reading, presumably, since his

Somo of Edison's Trensures, 


This Wbrary room wlth [ts finkshlngs and 
furnishings, a framed card informed us, was | 
a gift to Mr. Edlson from all of the present 
and some of the past employes, Everything 
fs In onk, hard wood finish, ‘Che cane-seated 
oak chairs have Mr, Edison's monogram 
carved on the back. There are two gale 
Jerlex, on the second of which Is the $40,000 
collection of mntnerals exhiblted by Tiffany 
at the Parls Exposition and purchased by 
Mr. Edison. Almost the outire space on one 
side of the room I# taken up with an cle- 
xantly tiled Mre-place, in which terra-cotta 
logs resting on splendid wrought fron 
stands are apparently belng consumed by 
ortlitclal gas, Over this fire-place $s ono of 
the finest speelmens of wood carving, fn 
way of a mantel, sald to be In this country, 
and it was done hy homo talent. 

‘The eutire space from top of mantel to 
ceiling Is Mled by the face of a clock carved 
fu oak, A bust of Humboldt in plaster oc- 





euples one end of the mantel, and a bronze 


figure of Sandow, with all bls wonderful 





museles showlug true to Ilfe, occuples the 
other, while between them, with spreading 
wings, sits on Amerlean engle that was 
brought from the Paria Exposition, where 
Its eyes had been Ilghted by electriclty. 
Tn the centre of this brary Is one of the 
largest—and Mr, Edison thinks the flnest— 
Pleces of statuary, both as'to enrving and 
conception, in the world. The sculptor waa 
Bordiga, and the subject’ is the Genlus of 
Electricity represented by 2 woman sitting 
on a street lamp putting out the gas and 
holding aloft a mammoth clectric bulb, 
which Is attached to a battery which stands 
at her feet atong with a telegraph iInstru- 
ment, telephone receiver, a book of acience, 
a cog wheel, ete. The walls are well cov- 
ered with pletures of men prominent in art, 
selence and Iterature. A whole page of 
TuE Tises, dated March 13, 1890, giving a 
“write up" of Mr, Edison, with I{lustra- 
tions, fs framed and hung up. Another frame 
contalns his certificate of membership in 
the New York Chamber of Commerce. An- 
other holds an autograph copy of “Amer- 
fea," written by the author In 1832, and 
presented to Mr, Edison In 1894, 


Other Fontuves of the Work. 


Woe could spend al! ottr tlme in the Mbrary, 
but must hurry on to the great room na full 
of machinery as a watch {g of works, aud to 
the drawing room, where several men are 
continually maktug drawings for new ma- 
chinery, for be it known Mr. Edison Is 
Worklug out of electrical. and Into mechan- 
Jeal Inventions, We atl know of his inyen- 
tlon for extracting fron ore from the rock 
for the New York, Pennsylvania and Great 


- Bake [ron trade and the predictions that 


Mr. Edtson’ waa wasting his fortune in this 


j enterprise, and we know the ore is now 


being taken out by the freight car load and 
that tho stock of the corporation Is on the 
Jump, 

We saw the great wooden moiels of a 
sand separator and a atone’ crusher, and 
afterwards saw the wonderful machinery 
cutting the thing out In fron, whittling ang 
shaving as If the iron were plne wood, 
These seemed to us queer Inventlons for Mr, 
Edison, We had never associated him with 
this kind of work.: We felt.better satlsfled 
and more ag if we were with Mr, Edison 
when we were taken into a dark ‘room and 
allowed to see each other's heart by menns 
of the X-ray ‘and to hear clectricity made 
to crack Iike.a whip In the hands of a stago 
coach driver. But our cup of gratificatlon 
was filled to the brim only after we had 
visited Mr, Edison’s own private workshop, 
wherein we were told he had made 18,000 
experlinents with the Huorescent ray before 


i he got the X-ray, and the finprovements on 


the Crook tubes ng they nre used to-day, 
Wo had evidently left his work table In 


+a hurry to come to us and to leave to bury 


a 


{ hla dead employe, doubtless, for, there were 


many evidences of a hasty exit on. the 
table Itered with specimens of ore, bottles 
half filled with unknown substances and 
leayes from writing tublets-covered with fyg- 
ures, The place seemed full of the pervon- 
ality of the man. A fecllng of awe crept 
over us ag we realized that here Ilved and 
thonght and labored the man whose In- 
ventions have practically changed the face 
of the globe, who tins gained and spent 
milffons In doing It; who has been honored 
ag much if not more than any man now 
ving and whose wonderful falry-tale life 
raises the ol question as to whether the 
opportunity: makes the man or. the man 
‘makes the opportunity,:  ( . - .

close to $300,000,000, Bicycle and car-

Quick as ever to grasp a situation, the inventor has 
evidently forescen the need of just sith a machine,— 
one that will cost less than two iandred] ang fifty 
dollars, and consequently be within the medns of the 
horse-owner of to-day.. If the horse is ‘toibe super- 
seded, by the motor car, it must be by mbans of a 
vehicle that costs less thanthe animal. If itcpsts more 
it will not be generally used. ‘The cumbrous electric 
cab now used, heavy and inartistic as it is, tosts two 
thousand dollars, but it is Mr. Edison's. parpose to 
reduce the price, to five hundred dollars, a make it 
lighter, and more pleasing to the eye.” Once he can 
demonstrate that a cab can be“produced on {he:above 
lines, he will extend the pros @ to hundreds of other 
styles and sizes of vehicles, somé of which will be put 
on the market, in all probability, as low as on¢: hundred 
and fifty dollars apiece. 7 || 


The Approach of the Horseless Age * | 
“ "Something of the magnitude of the field in which 
i) Mr. Edison's efforts are now being directetl may be 
gathered from the figures of recent incorporations, 
Six companies are now organized, and thre¢ of them 
are engaged in the tianufacture of horseless: vehicles. 
‘The aggregate capital of the’ six companies ls eighty 
3 millions, Several kinds are made in.the United States, 
including gasoline vehicles and storage battery 
electric cabs. The average cost of the formeris twelve 


methods, ‘The great institution which he simply} hundred dollars, and of the latter two. thousand: dol-

struments that required the best skill. of Europe to 
produce. In the galleried library there are scientific 
volumes that cost their weight in gold. | 

Upstairs in the music room Raymonj);Moore was 
singing a tenor solo for record making while a dis- 
tingtished pianist accompanied him. A new engineer 
was being drilled in his work as 1 entered; Mr. Edi- 
son was doing the drilling. He never requires a man 
to do anything that he cannot do himselfy If his em- 
ployces were as good mechanics ‘as.he,,onb-half of hi 
tremondouslabors would be saved but, S itis, he is 
constantly obliged to be in attendance wien putting 








charged every trip of fifteen miles at consideranly 
more expense, ‘I'he automobile is rapidly assuming 
‘a detinite place in the public mind, and this condition 
is bound to result in an extended market as soon as 
construction can be simplified and the price reduced. 
The United States government has taken the first 
steps looking to the use of electric mail wagons. for 
both collection and delivery purposes. A company of 
capitalists in Morristown, New Jersey, has experi- 
mented with a view to establishing a regular Pas 
senger service in that city, neither cable nor tro! ley 
“lines having been permitted to obtain franchises there, 
It is proposed that automobiles shall do the same 





service there as electric street cars in other places, A 
great many wealthy men now own private convey- 
ances, and several physicians employ this means of 
answering calls quickly, but it can hard) y be said that 
motor vehicles are becoming common. England uses 
: ten to America’s one, while France uses a hundred to 
A England's ten. If the conditions mentioned ever pre- 
vail,—and it rests with such inventive genius as Mr. 
Edison’s to bring them about,—the day may not be far 
distant that will usher in a horseless age 


up a new contrivance, As I watched hig, his hands 
grimy with bluckened oi) and his pockets Bulging with 
nuts, bolts, and bits of machinery, I began to under- 
stand one of the ‘reasons for his marveléus success, 
He studies.everything and knows everything concern- 
ing-his inventions from the ground up.a 


Edison and His “Boys” 1 

Just now Mb. Edison is bending his talents to dis- 
covering a perfect cement, one that ‘shall take the 
place commercially of the article used by builders 
and in hydraulic construction. In addition, he 1s try- 
ing to perfect a motor-vehicle which shall be of popular 
price, ‘hese two are simply his leaders, '. The other 
six or eight inventions upon which he bestows daily 
attention are in connection with his great concentrat- 
ing works at Edison, New Jersey, where he is revolu- 
tionizing all known methods of crushing;iron ore,— 
and‘in-making improvements in-his phonographic and 
telegraphic departments. He works on thege improve- 
ments constantly, and no sooner is one perfected and 

atented than he starts on another.:’ His }'boys,” as 
he calls the two thousand employees of his various 
plants, need constant attention to kee ian going,

Unventors 





and of course Mr. Edison is notsatisfied with anything 
commonplace. He wants the several busitlesses to be 
‘up*to-date, and when competition comes. he. contrives 
something to put them ahead of their competitors, if 
human ingenuity can accomplish it. 5 

‘T think he expects to win the grandest success of his 
life in giving to the world an automobile that will be 
within the reach of the average person, He would not 
say this,. His well-known economy .of words,—in ad- 
vance of-the completion of.a triumph,—precluded any 
hope | might have had of an explanatory interview. -

{ DAMAGES, 


{ ° Fredrick M. Prescott, formerly head “of! 
» the Edigon Phonogr raph Agency, 44 Broad: 
i Street, has brought™suit in Chancery in j 
Le Jersey against Thomas A. Edison, . 
the National Phonograph Company, Wil- : 
| liam E. Gilmore, Charles E. Stevens, and 
; others, for.a “conspiracy to destroy” his; 
- business. ‘The complaint takes the fol-° 
i lowing: allegations: 
“In' 1894 Prescott bégan selling phono- | 
jerepne for. export... His business grew ¢ 
!rapidly, and in the Autumn of 1897, | 
| Wittiam E. Gilmore, general manager of | 
ithe Edison Phonograph Works at. West } 
Orange, N. J., solicited him -to’ ‘purchase i 
! phonographs: of” that. company, and, to: 
i quote, the complaint, :‘* offered to sell’ your | 
.orator’at lower prices than any other cus-"| 
‘tomer, so that it was to the interest of your 
orator to cease buying phonographs of the 
i United States Phonograph Company, and 
‘to buy of the National Phonograph Com- 
pany; that your orator was then buying 
about five thousand dollar's worth of phono- 
| graphs monthly of the United States 
Phonograph Company, and that it was to | 
| the interest of the National Phonograph: 
Company and the Edison Phonograph 
: Works to secure your orator’s trade; for the 
‘teason that they would thereby increase 
‘ their sir trade, inasmuch as the machines sold 





to? your orator were by him ressold in foreign 

; ‘countries, where’ithe Edison Phonograph 

\ Works.and the: ‘National Phonograph Com-: 
pany could: pot lawfully sell;phonographs. ’ ‘| 

With: liBeraldiscounts” ‘allowed to him, 

_ Prescott says s that he rapidly worked up an 
extensive foreign trade, and became one of 
the largest customers of the Edison Com- 
pany. ‘This success led, he says, to the 

. conspiracy to force him out of business so 
that the profits might be diverted to the 
National Phonograph Company. 
According to the complaint, the first 
. positive step was in the Spring of 1898. | 
The complaint says that Charles E. Stevens, ! 
who ‘had previously made himself useful: 
in copying for the Edison Company the list | 
of customers of a rival, the United States ' 
Phonograph Company of Newark, came to, 

'“him‘and, said: ‘That neither he nor Mr: 

. Gilmore: nor Mr. Edison-.was satisfied-with’ 
‘the manner in which your orator was con- 
2 ducting his business, and he stated that he : 

: ewas about ready to resign his position with ‘ 

‘the!National Phonograph Company and to | 

go:into the export business in phonographs : 

in’ competition with your: orator; that a 

large | export house in the ‘City of New 

ork had offered to fit - ‘up an office for the 
said’ Stevens in’ “New York at its expense, 
furnish him-with capital to conduct the. 
uusiness, to put him.in-chargeof. the said— 

“office, and to divide the profits with iim; 

} that the said Stevens stated that he was 

ready to receive a proposition.” 











fs 












Prescott says that at that time he was 
'-so dependent on the Edison Manufactur- 
ing Company that he yielded to the threat 
} and took: Stevens in as a partner. ‘The 
*Jatter put-in no money, but received a 
-salary of $50’ a week, drew out $2,881 
"profits in less than four months, und took 
'.$1,281 as his share of the assets when the 
..firm dissolved, 

*’ In August, Prescott went to Europe for 
a three months’ trip. Troubles fell thick 
‘at once. When he landed he received a 





t dispatch saying Stevens demanded a dis- 
t: ;solution of the partnership by Sept. 1, and 
i another that all discounts had been with- _ 
drawn. Prescott hurried back, reached 
New York Sept. 2, and the partnership 
“was dissolved immediately. While he was

customers, 


Later Gilmore notified him. that lie could : 


not .use:‘the* name “Edison Phonograph 
Agency," and Mr. Edison wrote a letter to 

: Postmaster Van Cott in which he said: 
: “T have recently received some letters 
, ! from foreign countries calling my attention 
to the fact that people who sent him mon- 
1 eys had received nothing in return for 
' them, and one of the parties who has writ- 
ten me advised that he had written the 
Chief of Police of New York City to look 
into the matter. I consider that the young 
man is using the mails to further his own 
ends and to hurt my very good reputation. 


4 sears 
| away, he alleges, : ‘Stevens copied his list of 


I would like to know from you if it is not, 


possible for you to arrange to divert all 


mail addressed to the ‘Edison Phonograph 


Agency,' New York, to the company who 
has the right from me to handle the phono- 
graph business; this company is the Na- 
tional Phonograph Company, ‘I'wenty- 
sixth street and Broadway, New York.” 
Prescott says that Mr. Van Cott investi- 


- gated the matter and refused to turn over : 
| his letters to Mr. Edison’s company. The 


‘complaint closes with a prayer for an in-

200 square miles containing gold worth 

$800,000,000 that would have remained there 

had this process not been discovered. That

the world's supply. There are large deposits 

‘elsewhere that the process will also make

man. Mines could not be worked In that! 
region’ without water, and the cost of get- 
ting $100 worth of gold from this land by.

value of the metal, The machinery which

say about the proposed steam rail con- ; 
nection with igeleville. As for as

‘figare, It means much to Warren 
county, in general, and Washington, in 
particular; and our people will be glad 
to see it realize the expectation of Mr, 
Edison and those associated with him. 

Below will be found a few remarks 
by another writer concerning the con- 
templated mill and’ the cement in- 
dustry. . 

AS OTHERS SEE IT, 

‘Thomas A. Edison has stated that 
the big cement plant about to be erect- 
ed between Stewartsville and New 
Village would be one of the largeat in 
the United States, and that it would be 
equipped with modern machinery. 
Arrangements are being made‘ to com- 
mence the construction of the huge 
buildingsinthe spring. . es 

“fhe importance of this brief: an- 
nouncement might. says the Phila- 
delphia Record, be readily overlooked 
without some further explanation, 
which may be, perhaps, afforded by a 
brief description of a very recent visit 
-to‘Edison’s laboratories at Orange, :N. 
J., where a complete model of the new 
cement plant alluded to, constructed 
upon a scale of two inches to the foot, 
or.one sixth of the full size, making, 
perhaps, the largest model of ‘a ‘im 
ever built, was shown by Mr. Edison 
himself. ‘In the first place, it may: be 
said that ‘the term ‘laboratory?’ fails 
tocorivey any adequate idea of: thie

_ TEE PORTLAND CEMENT INDUSTRY, |” 
‘One year ago the Engineering and 
Mining Journal in its annual issue, 

iving the mineral statistics of the 

nited States for 1898, said, oj 2: 
...The greatly increased demand for 
+Portland cement in the United States 
}in 1898 led to a depletion of stocks and 
_ taxed the domestic productive capacity? 
‘to its utmost. At present the acturl’ 
, production is less than the current con , 
‘sumption, and stocks are very small, 
“The increase in consumption is attri- 
butable partly to the extraordinary re- 
:guirements of the Government: and 
“partly to the extensive construction of 
puildings, dams, bridges und otner 
large works. It is noteworthy that 
‘the cement is taking the place of ime 
and mortar in a,good deal of construc- 
tion work, Notwithstanding the large 
increase in the domestic demand, the 
{mportation of foreign: Portland ce- 
ment fell off from 2,787,760 barrels in 
1897, to about 1,700,000 barrels in 1898,, 
which shows the extent to which Amer-: 
ican producers now control the Port- 
land cement business of this country. 
OF course, the existing conditions led 





} to an increase in prices, and American 


Portland cement ranged between $1.90: 
and $2.26 per barrel in New York dar-, 


‘ingithe year. Imported cement sold 
a eae 32,25, against $1,90@§2.10 in 
1897. 5 + 


“The increase in the consumptive de- 
mand was a great stimulus to the. in-, 
dustry, and several new concerns were. 
induced to engage in business, while. 

- many of the older manufacturers made: 
preparations to increase thvir output 
Jargely. The Lawrence Cement Oom- 

:pany began in October the erection of 
a large new plant at Siegfried, Pa.; the; 
Coplay Cement Company commenced ; 
‘the ‘erection of an additional, plant, 
with a nominal capacity of 1600 barrels 
per day, while the Atlus Cement Com- 
pany, at Northampton, Pa., made pre- 
‘parations to double its capacity..and 
turn out 2,000,000 barrels in 1899, ad- 
-ding 32 new kilns to its plant... -.2.. 3... 
‘The total production of Portland. 
cement in 1898 in the United States was 
stated to have amounted to, 8,584,686 
barrels, containing. 400-. pounds @ube 
The annual statistical ; number of. tuis: 

Journal, just issued, gives :the produc-| 
tion in 1809, at 6,146,084 barrela of. 400 
pounds each. Satie ono 
‘03. AN INTERESTING MODEL. |‘ = | 
-; The model of Edison’s hew.’cement 
mill already alluded to is jcontained ‘in 
a building especially constructed for 
the purpose and some idea of- the size 

‘of the mill, which is to be ‘built entire: 
lyof steel, may be gained when we say: 
that the model is about .110 | feet: lon: 
and hos. number..of. wingg\abont 4 
feet in length -placed-atrigut:angles 

‘the main building, the intention being 
to enlarge the plant from time to time 
by. building new. wings.. When all the 
wings shall have. been. completed:.the 
mill will have a. capacity, so it. was 
atated,- of 1000,barrels a day. But,-.as 
paginelly constructed the output. will, 
be far less-than this, althongh the main 
portion. of the mill will.be of. full..size., 
* Mr.:‘Edison’s reason;for,constrnoting. 
so large and costly a. model is in order, 
that he may be able.to, eae. day, by da: 

every, detail of the new features, whiob; 

‘will be introducedand study the modesl:

re , 18 to make the mill so complete 
uw iteelf that human labor will be 
practically eliminated; in other words, 
almost ali of the operations will be 
automatic; furthermore, they will be 
continuous, go that, once started, the 
mill may keep on day and night turn- 
ing out the best gra eof Portland ce-! 
'ment, packed in barrels ready for ship- ; 
ment, as long ns it shall be kept sup- 
piled with the raw materials, The 
arrels will be made on the spot in one 
‘or more of the wings. The whole ar- 
rangement of the machinery for grind- 
the materials, mixing, roasting and 
conveying them from point to point, 
even tothe final packing of the, pro- 
duct, isclearly shown in the big model, 
and it is expected that all experiment- 
al work necessary to develop any 
defects and show where changes may 
be made to advantage will be fully 
exploited and developed by means of 
working model, so that the big mill it- 
self, the first ofits kind, will be con- 
atructed on permanent lines. This 
feature is, in point of fact, character- 
istic of all of Mr. Edison’s experiment- 
al work and is largely the secret of 
his phenomenal success in under- 
takings which, in less competent 
hands, would have been doomed to 
failure even if they had proved’ en- 
couraging in ordinary laboratory tests, ; 
Tn various other departments of the es- 
,tablishment actual working tests were 
‘being made of some of cement mix- 
ing. machines and other apparatus, for, 
although we have called the big model 
a “working model,” itis not intended 
toactually make the cement in the 
model mill, but merely to operate 
upon a “dummy” material, to show 
the general principles, just as a huge 
working model of the eye may illus- 
trate to an audience of medical stu- 
dents the phenomenon of sight with- 
out actually having in itself any visual 
power. It may be said, in conclusion, 
that one of the unique features of the 
Edison establishment is the conjunc- 
tion or combination of purely experi- 
mental work, conducted on a small 
acale, and the manufacturing of Edi- 
ron’s specialties on a wholesale scale. j

THE MANUFACTURE OF EDISON PHONOGRAPH 
REGORDS, 

The Edison phonograph has hecome such a familiar 

object in our modern home hfe, and its mechanisw, in 
spite of ita marvelous ingenuity, isso straightforward 
and,ensily dnderstood, that it is difficult, in giving a 
description of this prince of toys, to tell the multitudi- 
hous possessors of them anything that they did not 
know before,. If one were asked to naie the particu- 
tar part of the phonograph which possessea the great- 
est interest and which is the most essential to its suc- 
cess, he would have to mention the cylinder of wax 
upon which the waves of sound are cut by the dainty 
little sapphire turning-toolfknown as the stylus, 
- The great growth in popularity of the pliono- 
graph, and the necessity for keeping the {owners sup- 
plied with fresh “‘Hterature,” bas caused the mere 
work of manufacturing the records to assume truly 
enormous proportions, Evidence of this is shown in 
the storage room of the Edizon Phonograph Works, in 
which are to be found tier upon tierof storage “bins,” 
whose contents represent records of 8,000 distinct sub- 
jects, or nearly half a million wax cylinders fn all. 

The first process in the manufacture of records takes 
place in the melting room, where the proper constitu- 
ents to forin thespecial grade of wax employed in mik- 
ing the records are brought together aud melted in 
several large vats, each of which contains about 1,000 
pounds. There aro three meltings in all, and between 
each the fluid is carefully strained to remove any hard 
or gritty impurities which it might contain; for it is 
evident that the presence of foreign substances, even a 
few purticles of fine dust, wight easily produce fatal 
irregularities in the grooves of- the record. ‘Tho first 
two meltings take place in the melting room, and the 
third in the moulding and shaping room, of which we 
On entering this room, the 
most conspicuous feature is several lnrge, circular, ro- 
tating tables, set around the periphery of which is a 
number of round, iron pins which forw.the core of the 
mould, Concentricatly around each of these ping is 
placed a brass sleeve. The wax is taken from the 
melting vats in acan and poured into the moulds in 
the manner shown in our illustration, ‘The tables are 
constantly rotated, thus bringing the moulds, which 
cool very rapidly, round to the workers on the opposite 
side of the table, where the wax cylinders are removed, 
Tho moving table brings the empty moulds back to 
the starting point, where they are again filled from the 
pouring can, The cylinders are cast with an interior 
spiral thread, which adds somewhat to the strength of 
the cylinder, and forms the bearing surface when the 
wax cylinder is placed on the wandrel of the phono- 
graph. ‘After they have cooled, the cylinders are first 
reatned out to gage, then edged and rough-turned, and 
finally given a finishing cut, the finish turning being 


’ done with a fine sapphire knife, ‘The records are then 


given a final inspection, in which those that show tie 
least sign of imperfection, such as a hair crack, or a 
fullure to meet thé gage test, are rejected. The 
cylinders are now ready for the important work of 
making the records. 

It should be mentioned just here that in addition 
to the standard size of records, measuring about 214 by 
4 ches, with which the public fs more familiar, the 
Edison Company wanufacture a.larger size, known as 
the concert record, which is about & inches {n diame- 
ter. The advantage of the larger size is that the 
grooves are longer and the curves of the depressions 
are of longer radius, with the result that the ball-point 
of the reproducer is able to follow the grooves more 
closely and give a more perfect reproduction of the 
sound waves. . 

One of the upper floors of a large building in the 
record department is divided into a number of rooms, 
in which the specialists who are employed by the Edi- 


son Phonograph Works are kept steadily at work . 


speaking, playing or singing into the recording ma- 
shines. One of our itlustrations shows the methods 
adopted in producing solo records, whether instru- 
mental or vocal. In this case the violinist stands with 
his instrument fimmediutely and closely in front ‘of 
three converging horny, each of which connects with a 
recording phonograph. The only difference between 


a recording and a reproducing phonograph is in the’ 


nature of the little sapphire tool by which the dia- 
phragm rests upon the wax record, In taking the 
record, the “recording stylus” is used, and in repro- 
ducing the record, the “reproducing ball” is substi- 
tuted. The difference between the stylus and the ball 
is that the point of the stylus ia cup-shaped and 
ground to a fine cutting edge, which, as it travels over 
the surface of the wax cylinder, ts driven wore or less 
deeply into the material, and turns off a shaving which 
varies in thickness, according to the quality of the 
sound waves which fall upon the diaphragm. It is ex- 


* tremely interesting to watch the endless stream of fine 


hair-like turnings which falls from the little tool while 
the record is being made. One of the first things 
that strikes a visitor to the record room is the rapidity 
with which the artists sing, the speed being much 
greater than that to which one fs accustomed In o 
music hall or opera house, Moreover, the songs are

sung with the full power which would be used before 
a public audiences, As soon as the record is made, it is 
taken off the mandrel and placed in a phonograph 
and reproduced to test its quality. If there is the 
slightest defeot, it is, of course, rejected. 

Among the most popular records are those of band 
musiy, and for making these the company maintains a 
full instrumental band, which is ocoupled steadily, 
under the,baton of a conductor, in playing popular airs, 
marches, waltzes, ete, The tnusicians are so grouped 
around the phonographs that the volume of sound 
from each instrument strikes full upon the horns, the 
front row of the performers being seated on ordinary 
chairs and those behind on raised seats, Of tho occa- 
sion of our visit there were no less than sixteen phono- 
graphs on the racks in front of the band, each with its 
horn pointing toward the musicians. In this case, as 
in the case of solos, the inusic is performed at full 
power, 

The testing of the phonograph records is done in a 
separate room by a corps of experts, who are careful to 
throw out every record that gives the slightest sugges- 
Long training in this work has made 
them sensitive to irregularities in tone and quality 
which would scarcely be noticed by the average listener. 
It is to this searching examination that the uniformly 


high quality of the Edison records is largely to be - 


attributed, 

Our Inst illustration shows the phonograph test- 
ing room, This test is just as important as, and per- 
haps more so than, the testing of the wax records 
themselves. ‘he work done in this department is 
really a matter of testing the testers, for during the 
construction of the machines every part of the phono- 


graph, as it, is completed, is subjected to close inspec- . 


tion, It may happen, however, that in the assembling, 


- or in the frequent handling, a trifling injury may have 


resulted to some part; there may be uw slight lack of 
adjustment, or the bearings may be clogged with oil, 
and it is the nart of the final inspector to detect such 
faults and see that the machine works with tho abso- 
lute smoothness necessary to good phonographio re- 
sults, 

The phonographs themselves, after passing this test, 
are put in cabinets and sent to the shipping depart- 
ment; the phonograph records, efter the final inspec- 
tion, are each carefully wrapped in cotton, then in 
paraMne paper, and finally pinced in cardboard boxes 


‘on which are printed the catalogue numbers of the 


records, The boxed records are then stored in num- 
bered bins, and on the receipt of an order, it is a sim- 
ple matter to select the records, pack them in cases or 
barrels and wheel thei to the cars, which are brought 
by a switch to the doors of the shipping departinent, 

In closing we would make mention of the really ad- 
wirable syatem of shop management which is displayed 
throughout the whole of the works—a system which 
displays very markedly that characteristically Ameri- 
can arrangement of the shops themselves, and of the 
machines with which they are crowded, which alts at 
wininizing the amount of handling and transpurtation 
to which each individual piece is subjected in its trans- 
formation from the crude material to the finished arti- 
cle. There are, as this journal has often pointed out, 
several elements which conduce to the commercial su- 
premacy of the country; and to nothing is the cheap- 
ness of our products more directly traceable than to 
that carefully-thought-out distribution of the work 
and orderly and consecutive arrangement of the ma- 
chines, of which these works are a striking example,

Sictonce Notea, 

Mr, Marshall H. Saville, of the American Museum 
of Natural History, has started for his winter work in 
southern Mexico, where he will continue his exeava- 
tions in the territory formerly occupied by the Zapo- 
tecans, 

An institution was opened In Belgium for the alleged 
cure of tuberculosis by the exclusive raw meat diet. 
After a trial of a few months, the experiment was 
abandoned, oa it was found that there was no efficacy 
in the Richet cure, 

The various solentific departments in England re- 
cently held 2 conference in which they sought to obtain 
government powers for protecting the delicate inetru- 
ments in the Kew and Greenwich observatories from 
any magnetic disturbances that arise from the work- 
ing of electric tramways and railways in thelr vicinity. 

The Duke of Abruzzi on his recent Arctic expedition 
carried with him a sinall balloon, stmilar in con- 
struction to those employed in the Italian army, for 
the purpose of pushing farther north when the vessel 
became blocked bythe ice. It, however, proved use- 
less, The duke fs now busily engaged upon the design 
of a new balloon, specially adapted for such an object, 
which he will take with him upon his next expedition. 

There is to be a ceramic exhibition In St, Petersburg 
in December. Its aim is to show the public the pro- 
gress wade by Rugsin and other countries in artlatio 
and industrial ceramics, Only works of artistic excel- 
lence will be admitted to the exposition, but also 
those which, Iucking the preceding condition, ara yet 
distinguished by the originality of their design, forin 
or mode of manufacture. 

The elty budget of New York city for 1901 calls for 
the expenditure of $08,100,418 43, an increase of $8,821,- 
440.05 over the budget for 1900. The largest suis are 
for education, $18,512,817.60; interest on city debt, 
$12, 100,200.05 ; police, $11,083,313.42 ; the redemption of 
the city debt, $10,882,173,18. It is curious to note that 
The City Record, in which various advertisements re- 
lating tothe city are printed, has $503,200 appropriated 
for it, an enormous sum, exceeding that appropriated 
for buildings. 

Sir George Newnes, who financed Mr. Borchgrevink’s 
recent expedition to the Antarctic zone, has placed the 
whole of the scientific spoils collected by the late 
Nikolai Hansen, the scientist to the expedition, at the 
disposal of the Natural History Museum at South Ken- 
sington. ‘The collection comprises birds, bensts, fishes, 
and an assortiuent of other innumerable curiosities, 
‘The authorities at the museum will select all that they 
require, and transfer them to the experts in the respec- 
tive departinents, to be duly examined and annotated, 

At a recent congress of German anthropologists, 
which was held at Halle, Professor Dr. Klaatsch, of 
Heidelberg, read a paper in which he contended that 
the hypothesis of the direct descent of tan from apes 
was no longer tenable. His conclusions were based 
upon the biceps muscle of the thigh. He stated that 
it wasa mistake to regard man ns the most perfectly 
developed mammal in all respects. His limbs and 
teeth do not show any high degree of development, 
and he is superior to other animals only fa his brain 
development. 


The Rev. J. M. Bacon, F.R.8., proposes to make 
& balloon ascent during one of the thick, fmpenetrable 
fogs which visit London during the winter’ months. 
He proposes to ascend to the higher limits of the 
fog and to explore scientifically its constitution, He 
also proposes to discharge small cartridges of cun- 
cotton at great heights, in order to ascertain whether 
the concussion will dislodge or disperse the fog in any 
way. He has already carried out several experiments 
with similar cartridges for acoustical purposes, at vary- 
ing altitudes. ; 

Arrangements are being made among the various 
scientific and mechanical institutions in London to 
hold an engineering congress at the Glasgow Exhibi- 
tion next suuimer, The congress will consist of nine 


’ sections, with Lord Kelvin as Honorary President. The - 


President of the Institution of Civil Eugineers will pre- 


“side over the first section, while other sections will be 


presided over by Sir Benjamin Baker, I.R.8., and 
Sir John Wolfe-Barry, P.R.S. Already a sum of over 
$10,000 has been collected as a guarantee fund for de- 
fraying the expenses of the scheme. 

The latest development of the automatic machine is 
an apparatus in which letters and telegrams may 
be placed to await,.the call of the addressee. The com- 


- munications are inserted in the machine in such a 


manner that the name and address is plainly visible 
through a small window. To obtain possession of a 
missive, one places a penny in the slot, Should a re- 
ply be necessary, the insertion of another penny into 
the instrument will insure the delivery of an envelope 
and sheet of note paper, and the reply may be written 
upon a sinall desk attached to the machine, It is 
stated. that the English postal authorities have con- 
sented to place letters and ‘telegrams in these auto- 
matts ‘' postes restantes” if the address of the particular 
machine is scented:

The history of the telephone furnishes 
complete justification of the United States

the constitution “to promote the progress 
of the sciences and useful arts” Bell for 
17 years held the control and secured the

Mr. Edison’s Reminiscences of the 
First Central Station. 


R. THOMAS A. EDISON is not 
M an easy man to find at home. 
~ During the day, and often far 
info the night, he is at the big 
brick Jaboratory building in Orange, 
N. J., and this building is surrounded by 
avery high and discouraging picket fence, 
in a remole corner of which is a gate and 
nearby a push-button. Once through this 
—and it is hard to get through it-—various 
dragons lie in wait for the bold person who 
undertakes to interrupt one of the busiest 
men in the world. 

Once inside the visitor is conducted into 
a spacious and lofty library. where he 
waits. Here, after a time, comes to him 
the genius of the place, and go it was when 
Mr. Edison talked with one of us the other 
day about the starting of the Pearl strect 
atasion in New York city and the birth of 
electric lighting as an industry. 

The passing of time has left few marks 
upon the veteran inventor; perhaps his 
hair is a little grayer, hut he entered the 
library with a springing step that would 
have done credit to a boy, and hailed, his 
visitor with a flash of the old-time enthu- 
siasm, 

“So you want to talk about the old days 
at Pearl street,” said he. “Well, I hardly 
know where to begin. Jt waa something 
like this; the central station idea struck 
me all of a sudden in 1878. In those days, 
you know, we had are Jamps. I had been 
down to see Professor Barker, at Phila- 





detphia, and he had shown me one. A 
little later T had seen another onc—I think 
it was one of Brush’s make—and the whole 
outfit, engine, dynamo and one or two 
Inmps, was traveling around the country 
with a circus. At that time Wallace and 
Moses G. Farmer had succeeded in getting 
10 or 15 lamps to burn together in series. 
It happened that I was comparatively at 
leisure then, because I had just finished 
working on the carbon button telephone, 
and this electric light iden took possession 
of me. It was easy to sce what the thing 
needed; it wanted to be subdivided. The 
light was. too bright and too big. What 
we wished for was little lights and a dis- 
tribution of them to pceoplo’s houses in 
just the same way that gas is sent around 
and burned at your fixture when you want 
it. I remember, along about then, Gros- 
venor P, Lowry thought perhaps I could 
succeed in solving the problem and he 
raised a little money and formed the Edi- 
son Eilectrie Light Company. We started 
the laboratory at Menlo Park. The way 
we worked it wag that I got a certain sum 
of money a week and employed a certain 
number of men, and we went ahead to ace 
what we could do.” 

Replying to an inquiry as to how he 
went at the problem, Mr. Edison laughed 
‘and said, “Why it was casy. It was ensy 
enough to see that the subdivision never 
could be accomplished unless each light 
was made independent of every other. 





Now it was plain enough that they on 
not burn in series; hence they must. | 
in multiple arc. It was with this c:: 
viction that I started. I was fired 

the idea of the incandescent Inmp as «- 
posed to the are Iamp, so I went to \~- 
and got some very fine platinum w: 
drawn. As well as I remember it wi 
made by Johnston, Mathy & Company, } 
London. We tried to make the platinu: 
work but it didn’t stand. Then we !re 
mixing in about 10 per cent of iridiu:. 
with the platinum, but we couldn't fire. 
that high enough without melting :: 
After that came a lot of experiment: 
covering the wire with oxide of cerium an? 
a lot of other things such us the Welsha:: 
people use nowadays, Then I gota y:.\' 
idea; I took a cylinder of zirconia nw: 
wound about 100 fect of the fine pls:: 
num wire on it coated with magnesin from 
{he syrupy acetate. What I wos air 
was getting a high resistance lamp and ! 
made one in that way that worked up to 
40 ohms; but the durned oxide developed 
the phenomena that Dr. Nernst has run uf 
against lately—I didn’t see i then na he 
does now—and the lamp short-circuited 
itself! 

“After that,” continued ihe inventor, 
warming to his subject, “we went fishing 
around and trying all sorts and shapes of 
things to make o filament that would 
stand. We tried silicon and boron and s 
lot of things that T have forgotten no

‘was what kind of carbon. 


January 12, 1901 


The funny part of it was that I never 
aught in those days thal carbon would 
vaswer beenuse a fine lait of curbon was 
-o sensitive {to oxidation, -Jinally I 
shought I would-try it beenuse we had got 
very high vagua and good conditions for it. 


There were quite n Jot of us in those days 


that used to tulle things over together at 
Mento Park. ‘There was Charlie Iuglies, 
and Bachelor, and Upton and poor Kruesi. 
C. §. Bradley came with us a little later, 
‘a our central station work, 

“Well, we sent out and bought some 
otton thread and carbonized it and made 
che first filament. We had already man- 
aged to gel pretty high vacua and we 
shought maybe the filament would be 
anble. We built the lamp and lighted it; it 
.it up, and in the first few breathless min- 
ties we measured its resistance quickly and 
found it was 275 ohms—all we wanted. 
‘Men we sat down and looked at that 
lamp; we wanted to sce how long it would 
turn, ‘Phere was the problem solved—if 
the filament would last. ‘fhe day was— 
ict me see—October 21, 1879, We sat 
md looked and the Jamp continued to 
urn and the longer it burned the more 
fascinated we were. None of us could 
go to bed and there was no sleep for over 
10 hours; we sat and just walched it with 
anxiety growing into elation. It lnsted 
about 45 hours and then I snid (1£ it will 
burn 40 hours now I know I can make it 
burn a hundred.’ 

“There we were. We saw thal carbon 
was what we wanted; the next question 
I began to try 
various things and finally I carbonized a 
little strip of banboo from a Japanese fan 
and found that that was what we were 
seeking.” 

Uwasevident that Mr. Mdison was pleased 
vs he recalled these early days of the in- 
enndescent lamp and the joy of ereation 
that he must have felt in reaching his de- 
sideratum at last; but the lamp was by no 
means all, He continued, “I had the cen- 
(ral station in mind all the lime. I want- 
«i to use 110 volts. Now there is no use 


for you to ask me why, because I don’t 


know, but somehow that figure stuck in 
ny mind and I had calculated that, if we 
could get the voltage that high, the copper 
cost would be somewhere within sight. I 
got an insurance map of New York city. 
Did you ever see one? Muny big fat 
volumes, full of plaics, with every elevator 
shaft and boiler and house top and fire

Broadway to the East River; but what I 
wanted to know was whether my lamps 
could be made in quantily and depended 
upon, We went to work and imade up a 
lot of them. W. J. Hammer had charge 
of the tests aud they seemed to work out 
all right. ‘hen it was that we invited the 
Bonrd of Aldermen out to Menlo Pack.” 
Here Mr, Edison chuckled. “It was a 
great day,” he said, “or a great night, 
rather. 1 have forgotten the exact date, 
but it was cither the second or third of 
January, 1880, ‘he alderinen came out 
in n special train from New York and the 
first thing they saw were the strects of 
Menlo Park all lit up with incandescent 
lamps. You know,” he explained apolo-

geticully, “Uhut there was a land specu- 
lation out there then. We had the lamps 
strung along on two big wires and we 
could light or extinguish one without af- 
feeting the others, and this was a thing 
that seemed magic to the aldermen. I 
remember that Mr. Hiram Maxim was at 
this exhibition.” 

Fron the way he smiled at the remem- 
brance, Mr. Edison must have enjoyed the 
aldermanic visit. He went on: “Ihe sta- 
tion idea was still mighty strong with me. 
Why, I knew where every hatchway and 
bulkhead door in that district of New York 
was and what every man paid for gas. 
How did I know? Simplest thing in the 
world. I hired a man to sturt in every 
day about two o'clock and walk around 
through the district noting the number of 
gas lights burning in the various premises; 
then at three o’clock he went around again 
and made more notes, and at four o’clock 
and every other hour up to two or three 
o'clock in the morning. In that way it 
was easy cnough to figure ait the gas con- 
aunption of every {enant, and of the whole 
district; other men took other sections. 
Simple, wasn’t it? 

*T found there was 760 freight hoists; 


“61 


like Sellers, I figured every one would have 
& motor. 

“We were now fairly committed to the 
lighting project and started in to build a 
central station, You can’t imagine how 
hard it was. ‘There was nothing that we 
could buy or that anybody else could 
make for us. We built the thing with our 
hands, ns it were. We went to work at 
Menlo Park and started v lamp factory. 
Poor Kruesi* was set to work making the 
tubes over in Washington street,‘and we 
hired a kind ofa second-class machine-shop 
in Goerck street end there started out to 
inake the dynamos. We went at it with our 
own money and credit.” Here Mr. Edi- 
son’s eyes twinkled and he said, “I believe 
it was mostly credit. Anyhow, we strug- 
gled nlong and we got the money put up 
for the Pearl street slation by starting the 
New York Edison Illuminating Company. 


‘I planned ont the station and found 


where it ought to go, but we’ couldn’t get 
real estate where it was wanted. Why, 
man, they charged us $75,000 apiece for 
two old bum buildings down in Pearl 
street, where we finally settled. I tell 
you it made my hair stand on end. 
We had very little room and we wanted a 
hig output. There was nothing else for it 
hut to get high-speed engines, and, as you 
know, there were no high-speed engines in 
those days. I had conceived the idea of 
a dircet-coupled machine and wanted to 
hitch the dynamo direct to the engine 
without belfing. I couldn’t sce why, if a 
locomotive could run at that speed, a 150- 
horse-power engine could not be made to 
run 350 turns a minute. ‘The engine 
builders, when I asked them about it, hela 
up their hands and said ‘Impossible? I 
didn’t think so. Finally I found ©. H. 
Porter and I said to him: ‘Mr. Porter, I 
want 9 150-horse-power engine to run 700 
revolutions per minute.’ He hemmed and 
hawed a little while and finally agreed to 
iry to build it—if I would pay for it. I 


believe he charged me $4,200 for it. He, 


got it finished finally and sent it out to 
the Park and a fellow of the name of 
Ennis along with it. He was one of the 
nerviest chaps I ever saw. We set the 
machine up in the old shop and we had 
some idea of what might happen, so we 
tied a chain around the throttle valve and 
ran it out through a window into the wood- 
shed, where we stood to work it. Now, if 
you remember the old shop you know it 
stood on top of one of those New Jersey 
shale hills. We opened her up and when 
she got to about 300 revolutions the 
whole hill shook under her. We shut her 
off and rebalanced end tried again, and 
after a good deal of trouble. we finally did 
run up to 700, but you ought to have seen 
her run, Why, every time the connecting 
rod went up she tried to lift that whole 
hill with her! After we got through with 
this business we tamed her down to 350 
revolutions (which was all I wanted) und 
then everybody suid, ‘Why, how beautiful- 
ly it runs, and how practicable such an 
engine is? Now, don* you know, I knew 
they would eay that? Didn’t you ever 
find out that trying to do the impossible

makes about half the impossible seem 
easy? 

“We closed a denl for six engines and I 
went to work in, Goorck strect to build 
the dynamos onto them, Of course, we 
built them by guesswork. I guessed at 
110 yolts—and didn’t guess cnough. 
Thats why, if you want lo know, the 
extra pole pieces were put on those old ma- 
chines. They managed to lift the volt- 
age to what I wanted.” 

Going back to the Pearl street station 
idea, Mr. Edison said: “While all this was 
going on in the shop we had, dug ditches 
and laid mains all around the district. 
I used to sleep nights on piles of pipes in 
the station, and do you know 1 saw every 
box poured and every connection made on 
that whole job? ‘There wasn’t anybody 
else who could superintend it. : 

“Finally we got our feeders all down 
and started to put on an engine and turn 
over one of the machines to see how things 
were. My heart was in my mouth at 
first, but everything worked all right and 


,we had more than 500 ohms insulation re- 


sistance. ‘Then we sturted another engine 
and threw them in parallel. Of all the 
circuses since Adam was born we had the 
worst then! One engine would stop and 
the other would run up to about a thou- 
sand revolutions and then they would see- 
saw.” Mr. Bdison’s eyes twinkled with 
animation at the thought. 

“What was the matter? Why, it was 
those durned Porter governors! When 
the circus commenced the gang that was 
standing around ran out precipitately and 
some of them kept running for a block or 
two. I grabbed the throttle of onc en- 
gine and Jo, H. Johnson, who was the only 
one present to keep his wits, caught hold 
of the other and we shut them olf. Of 
courso 1 discovered then that what had 
happened was that-one set was running 
the other one asa motor. I then put up 
a long shaft connecting all the governors 
together and thought this would certainly 
cure the trouble, but it didn’t. The tor- 
sion of the shaft was so great that one 
governor still managed to get ahead of 
the others. Well, it was a serious state of 
things, and I worried over it a lot. 
Finally I went down to Goerck street and 
got a piece of shafting and a tube in which 
it fitted. I twisted the shafting one way 
and the tube the other as far as I could, 
and pinned them together. In this way, 
by straining the whole outfit up to its 
elastic limit in opposite directions, the 
torsion was practically eliminated and 
after that the governors ran together all 


right. 

“About that time I got hold of Gar- 
diner C. Sims and he undertook to build 
an engine to run at 350 revolutions and 
give 175 horse-power. He went back to 
Providence and set to work and brought 
the engine back with him to the shop. 
Tt worked, but only a few minutes, when 
it busted. That man sat around that 
shop and slept in it for three weeks until 
he got his engine right and made it work 
the way we wanted it to. When he 
reached this period I gave orders for the 
engine works to run night and day until

we got enough engines, and when all was 
reudy we started the engine. ‘I'he date 
was Seplember 4, 1882—a Saturday night. 
That was when we first turned the eurrent 
on to the mains for regular light distribu- 
tion and it stayed on for eight years with 
only one insignificant stoppage. One of 
those first engines that Sims built ran 
twenty-four hours a day, 365 days in the 
year, for over a year before it was ever 
stopped.” 

Questioned about the details of the 
work in those now ancient days, Mr. Edi- 
son snid: “Of course we had the whole 
thing to design in grogs and in detail and 
everything to standardize; there were me- 
ters, safety entches, fuses and alk the rest 
of it, but somehow we managed to work 
it out. At first we ha horrible misman- 
agement. ‘The only title to existence that 
such a concern had was ils aVility to make 
moncy, and we didn’t seem to make any at 
first. Finally IT went to Chinnock—of 
course you know who C, 1. Chinnock is— 
and told him that if he would take hold of 
the thing and make it work I, personally, 
would give a good big bonus beside his 
salary. Well, sir, that man pitched in 
and inside of eight or nine months had 
earned and received his bonus. 

“I don’t remember who it was who 
wanted to connect in a lot of places that 
used the light only occasionally, but some 
such establishments were on our mains and 
one of them was the Stock xchange. 
Now the Stock Exchange isn’t lighted very 
often and there were a good many lamps 
there. I remember that one day, along 
in the holidays, I think it was, we were 
loaded pretty well up to our limit and I 
was terribly afraid that that Stock Ex- 
change would have its lights turned on 
and overlond tis irretrievably. I was in 
{hat part of the town and all at once no- 
ticed that the Exchange people had turned 
on their lights. I-got to a telephone and 
ealled up Chinnock and asked him how 
things were. 

“Wow is it with you at the station?” 
said I. 

“«O, bully,’ says he. 

“Are the machines standing up to it?” 
T asked him. 

“ ‘Sure,’ says he, ‘but everything's red 
hot and the ammeter has made two revo- 
lutions I” 

Mr. Edison went on lo recount some 
of the details of the work. Those were 
the days of the old chemical meter which, 
ag every one remembers, contained two 
jars of a liquid solution which might, of 
course, if the weather became cold enough, 
freeze. “Those meters,” said the in- 
ventor, “gave us a good deal of appre- 
hension. I was afraid they would freeze, 
especinily in the water-front neighborhood 
where the commission houses are. You 
know those people there keep the front 
door open nll the year round and it gets 
pretty cold inside their places in the Win- 
ter time. So I went to work and put an 
incandescent lamp in ench meter case, 
with a thermostat strip that would make 
n contact through the lump when the tem- 
perature fell to 40 degrees. Well, you 
ought to have seen the trouble that that

simple thing got us into. ‘here can: 
along a cold snap of weather and the fir- 
thing 1 knew the telephone began to rin 
about every five minutes and people woul 
say: 
“Our meter’s red hot; is that all right - 
“Then another one would call up ar 


say: 

“Our meter’s on fire inside and + 
poured water on it. Did that hurt it? 

Asked about measuring instruments an 
methods of keeping the station up to a 
accurale and uniform voltage, Mr. Edi 
son snid, “Voltmeters? We didn’t hav 
any: We used Iamps. Once, down there 
we found our insulation resistance hiv 
golten down to 100 ohms; the director 
secined lo be seared, but I told them thi 
if it didn’t get below one ohm we were a! 
right. I used to have a good deal of trou 
ble with mathematicians at that time, bi: 
T found after a while that I could gue: 
a good deal closer than they could figure 
so I went on guessing. Why, in our carl 
work there we used to hang up a shingl- 
nail, tie it on g string alongside one of th: 
feeders, and use that for a heavy-eurren 
amineter, Tt worked all right. When th 
nail came close to the feeder we screws: 
up the rheostat a Jittle and kept the lain). 
in the station looking about right. 

“That was the time that I conccis' 
the notion of pressure wires running bar! 
from the distribution centres of the var: 
ous feeders. You know, in those day: 
Edison said with an apologetic smile, “ou 
lamps weren’t rugged at all. What tly 
wanted was just 110 volts, and not anoth: 
volt. 


“Yes, we were a good deal troubled * it" 
gelting fixtures and sockets and sum 
trimmings of that kind built right. Ber; 
mann had a little place on the east sist 
where he made gas fixtures, and he wer 
into making sockets and fixtures for 
and did well with them.” 

Here the conversation turned to day 
even older than those of the Pearl stre: 
station, and we talked a while about ds 
namo building in the Dark Ages. “Whi- 
T started making dynamos.” Mr. Edise: 
said, with an introspective look, “I «1 
told that to get the best effects the resis‘ 
ance of the machine must be equal to th 
of its lond! Did you ever hear of sue 
foolishness? I thought it was darn. 
alrange lo lose half of the energy I grt: 
erated in the machine, because what 1 w: 
after was to get the stuff out and sell i! 

T had an old Gramme machine anc 
worked over it. It had a terribly high r 
sistance. I figured out that if one tur 
on that armature would give one volt, ti: 
way she stood, by making great big mu 
nels I cowld get more volts, J went aber 
on that line and I remember I made om. 
litle machine that had a small armain 
nbout as big ag your fist and abont {. 
tons of enst-iron in its ficld ‘magnets. !" 
might not look like much to-day, but. : 
worked all right when the outside resis‘ ; 
ance was 30 times as big as that in th i 
machine. ‘That was what started me on 
the Inrgo field] magnets. T remember at : | 
dinner on the other side talking to We: | 
ner Siomens and Hefner von Altent: | 
j

and telling them that what we needed was 
a great big magnet to bring the juice out 
of the armature.” They agreed with me, 
bat,” and here he chuckled, “do you know, 
both of them said they had thought of it 
before? When I got back I went to work 
and made my magnets big and made them 
long—made them too long, as Dr. Hop- 
kingon found out forme. Ie was a great 
man and understood his job. Ie figured 
out that making the magnets short and 
cutting down the air-space was the thing, 
and he was right. After all, in those days 
all of us were guessing—and I happened to 
te a pretty good guesser.” 

We were led to speak at this point of the 
recent death of Mr. William H. Moore, 
who was once associated with Mr. Edison. 
This started Mr. Edison on some remitiis- 
cences of the hunt for materials for the 
filaments at the time when bamboo seemed 
the most promising, “Why,” said he, 
“[ sent a school teacher from Orange—I 
have forgotten his name—to Sumatra, and 
another fellow up the Amazon. He got 
stuck somewhere up there but worked his 
say over through Bolivia and got back. 
Finally, Moore went to Japan and got the 
real ing there. We made a contract 
with an old Jap to supply us with the 
proper fibre, and that man went to work 
and cultivated and cross-fertilized bamboo 
until he got exactly what we wanted. T 
believe he made a fortune out of it. I 
tell you, in those days the boys hustled 
hard. One man went down to Havana 
and the day he got there he was seized with 
the yellow fever and died in the afternoon. 
When T read the cable message that told 
of it in the shop ubout n dozen of the boys 
jumped up and asked for-his job! ‘Those 
boys were a bright lot of chaps and some- 
times it was hard to select the right ones for 
a particular piece of work. T once got an 

_ order from Mngland to send over 15 men 
eaperi in telephone work, so I went to work 
and rigged up some telephones and did 
al sorts of things to ’em. J would stick 
the point of a juck-knife through the in- 
aulation in spots and cut a wire, and in var- 
i-us ways introduce ‘hugs’ inte thoseinstru- 
ments; then the boys were set to work to 
find out what was the matter with them, 
Ifa fellow could find out 10 times inside 
of 10 minutes what the various troubles 
were he got his passage pnid and was 
atarted. . About one out of three of 
the boys managed to stand this test and I 
telieve that everyone of them who went 
abroad made money. This was back in 
1878 or 1879.” : 

Asked about his carly inventions before 
he began to work on the electric light prob- 
lem, Mr. Edison said, “When I struck the 
telephone business the Bell people had no 
transmitter, but were talking into the 
magneto receiver. You never heard such 
noise and buzzing ag thera was in those 
old machines. I went to: work and mon- 
keyed around and finally struck the notion 
of the Iamp-black button. The Western 
Union Telegraph Company thought this 
was a first-rate scheme and bought the 
thing out, but afterward they consolidated 
and I went out of the telephone business.” 

Asked about the invention of the fuse

ELECTRICAL REVIEW 


wire, Mr. Edison Jnughed as he recalled 
the first occasion for its use. “Why,” he 
snid, “the night those aldermen cume out 
to Menlo Park [ had figured that an inter- 
ruption would be serious and had thought 
out the scheme of putting some fine copper 
wire in as fuses in various places. ‘here 
was a fellow in the party—I won’t men- 
tion his name—and he had 2 little piece 
of heavy wire in his hand. While the 
aldermen were looking at some lamps 
strung between two bere inains this fellow 
walked up and short-circuited the mains 
with his wire. 1 believe he was the most 
surprised man of the party, because only 
three Iamps went out. ‘The reason that 
led me to think of the fuse wire was that 
we weren’t flush of dynamos in those days. 
I had burnt out two or three and I saw 
that something was needed to prevent that 
happening again. After my experience 
with my short-circuiting friend, I had 
fuses put in all over.” 

‘The talk turned to-the early days of the 
electric railway, and Mr. Idison said: 
“Yes, I was in that, too. I had a three- 
mile rord out there in 1883, and we used 
to pull freight cars up to the laboratory 
on it. We made as much as forty miles an 
hour at limes. Now that railroad project 
seemed to me to be a mighty good thing. 
You know I had a board of dlirsciars in 
those days—men with bulging foreheads 
—fellows that thought away ahead into 
the future, and I went to work and care- 
fully elaborated all the ideas I had for 
electric railways and submitted them to 
the board. ‘They considered the subject 
earefully and fully, and unanimously de- 
cided that there was no money in the elec- 
tric railrond and that they would let it 
alone! 

‘What was my first electrical inven- 
tion? You would never guess. It was a 
machine to record votes in Congress. It 
was a mighty good invention. I had a 
lot of iron type, each member’s name being 
set up in a line, and these lines were con- 
trolled by push-buttons and electromagnets 
so that each mun could bring his name 
up on the ‘aye’ side or, the ‘no’ side, as he 
pleased. I used ¢hemically sensitized 
paper to record them and the thing worked 
fine. A brother telegraph operator named 
Sam—I have forgotten the rest of his 
name—and myself were dead sure that 
we were going to ninke $50,000 out of it. 
He took the thing before 2 Congressional 
committee and the first thing they told 
him was that if there was anything on 
earth that the members of Congress did 
not want it was just that kind of thing, 
because the only right the minority had 
was to delay the game! After that expe- 
rience, which was in 1869, I knew enough 
not to invent anything again until 1 was 
sure it was wanted.” 

Going back to his own early history and 
the story of his connection with the elee- 
trieal field, Mr. Edison said that one of 
the first things he went into was a-mes- 
senger call-box or domestic telegraph sys- 
tem. “Wegot the thing into shape,” hesnid, 
“and made 200 instruments and then sent 
two men out to get subscribers, but they 
tramped around without avail day after 


63 


day and our hopes sank and sank further 
and further, Finally a man named Brown 
came along and the first day he tackled 
the job he got six. ‘This sent our hopes 
up again and after he got the lines londed 
up with subscribers we sold the scheme 


out and realized a good profit on it, Af- - 


ter that I worked ont the stock ticker. 

“What were my principal patents? 
Good gracious, man! Oh, you don’t 
mean patents — inventions? Why, first 
and foremost, the. idea of the electric 
lighting central station; then—let me ace, 
what have I invented? Well, there was 
the mimeograph, and the electric pen, and 
the carbon telephone, and the ineandes- 
cent lamp and its accessorics, and the 
quadruplex telegraph, and the automatic 
telegraph, and the phonograph and the 
kinetoscope, and—I don’t cea whole 
lot of other things.” 

There was only one time during the 
interview that Mr. Edison showed any 
signs of annoyance or impatience. ‘This 
was when he talked about some of the 
daily newspapers and their treatment of 
him. He said: “I’ve absolutely been 
obliged to set this watchdog system in 
operation, but the worst of it is that these 
fellows who come out here go back with- 
out ever having seen me or heard me speak 
a word and write out alleged interviews 
that make me seem foolish to people who 
don’t know me. 1 think it’s outrageous 
that I should be subjected to this kind 
of treatment. Interviews, so-called, with 


-me have appeared lately when I’ve never 


seen or spoken to one man connected with 
the sheet that prints them. I haven’t 
seen a reporter for a newspaper to talk 
with him for four years, and I want you 
to suy that every alleged interview that 
appears in the daily press of New York 
city us from ine is a fake, and that 1 have 
no responsibility for any of them. ‘There 
are two papers over there in particular 
that have annoyed me exceedingly and one 
in Philadelphia—a weekly —keeps its 
man coming here and coming here, but”?— 
and here Mr. Edison smiled meaningly— 
“the man will never get over that fence!” 

Asked if it were possible, in his. view, 
to achieve the direct production of elec- 
tricity from heat or from combustion 
without the intervention of mechanical 
agencies, he said: “Yes, almost anything 
is possible, and I really believe that some 
day we may get such a process that will 
show an efficiency of thirty or forty per 
eent. Some experiments we haye made 
over here have shown an efficiency of four 
per cent, and, as little as this is, it is cer- 
tainly promising.” 

Asked if he thought the achievement of 
the twentieth century would surpass that 
of the ninetcenth in invention, and espe- 
cially in the applicution of electricity, Mr. 
Edison, with a glow of enthusiasm, said: 
“Tt cerlainly will. In the first place there 
are more of'us to work and in the second 
place we know more to start on, bul, all 
the same, none of us knows anything about 
anything. We are ‘only starting, The 
achievement of the past is merely a point 


of departure and you know that, in our 


art, ‘impossible’ is an impossible word.”

THE STEEL TRADE AND NORWEGIAN 
ORES, 
el Z 
‘TO THE EDITOR OF THE TRS” 

Sir,—Tho lettor you published from dir. Lawrence 8 
fow days since in which ho announces tho successful com- 
pletion of Mr. Edison's mill for crushing and soparating 
Jow-grado iron ores withholds unfortunately sll thoso 
dotails which the mining world most wish to know. 

Thad on opportunity of discussing this mill with Bir. 
Edison io tho epring of 1894 at his lsborstory in New 

; Jorsoy, and he gavo mo his rossons for thinking the now 

‘ mill would rovolutionizo tho presont mothods of treating, 
not fron ores chicy, but also low-grade gold ores, Afr, 
Edison bad ovon then been st worl four or five yoars on 
tho mill, and ovidently rogarded its completion os tho 
most important offort of his lifo, 

Referring to tho notes I mado st the time I find that 
tho mill is 5 dry crusher, it welghs only nine tons, and 
will pulverize six thousand tons per day, the wholo of the 
particles passing through a “‘ fifty mesh” screen (2,500 
holes upon a square inch). The present crashing with 
stamps in tho Rand goldficld is to o fineness of 30 
mesh (nino hundred holes) ; each stamp crushes four tona 
por day and requires two-horse power. To crush to fifty 
mesh would reduco tho yiold per stamp more than ono 
half. Mr. Edison's Httle mill then does tho work of 
1,500 stomps ; it crushes nearly throa times as finoly, and 
this with only 350-horso power. 

I cannot say whother tho mill Mr. Lawrence 
ennounces 93 completed fulfils sll the conditions 

‘which Mr. Edison soven years since anticipated. It 
represents, howover, many years of unremitting 
experimont ond a vast sum of money, and coming from 
tho “ wizard of Menlo-park ’’ isa noteworthy dovclop- 
ment. Yours isithfully, 

MORETON FREWEN.* 

25, Cucsham-place, S.W., March 23, 


TO THE EDITOR UF THE TDILS. 
Sir,—The lotter of Mr. J. Lawrenco, which appears in 
your columnsof tho °5th ult.,having como cnder my notico, 
. I would bog Ieavo to point ont that the writer appears to 
( bo under cn illusion—misleading to others as woll as 
: himself—in supposing that Mr. Edison bss tho exclusive 
monopoly of any process for the magnotic separation of 
fron from its low-grado ores. 

Lhavo before mo documentary’ ovidenco that such a 
process is already, and fora Jong timo past has beon, in 
operation at Pitkiranta, in Finland, and that by it two 
tons of low-grade oro, containing 31°45 por cont. of iron, 
are concentrated to one ton containing 58°24 per cent. ot 
a cost of 2s, Sd. per ton. 

Tho oro yielding this particular result is not from 
the nowly-discovered field roferred to, estimated to con- 
tain €0 million tons, but from another part of tho Scandi- 
nuvion poninsula, as accessiblo to British ports, said ta 
contain 290 milllon tons of such ore—from afield which 
had been worked from time immemorial up to tho first 
helf of the 19th century. 

lam, Sir, yours obediontly, 
Aoril 2 F. DUFFEI™.

“| London letter to The Iron Age. 
“We have at last an authorized ‘statement 
&s8 to the Intentions and objects of the British 
syndicate. which: has been known to have a 
more or less organic connection with the Edison 
magnetic process, J, Lawrence, of the Ma- 
chinery Trust, and chairman of the Edison Ore 
Mining Syndicate,’ has’ made public the eitua- 
tion so far as his company $s concerned. From 
& mass of irrelevant detail, I subjoln the ma- 
terfal facts, as stated by the chairman: 
“Some three years 40 a number of us, large- 
Jy Influenced by the sclentific views of the late 
Dr. John Hopkinson, FP, 2. S., the electrician and 
‘engineer, became Interested, with Dr, Hopkin- 
s0n himself, in the dixcussiong of crushing and 
Separation of low grade iron ores, which Mr, 
Edison had been carrying on experimentally in 
America for. some years previously, and upon 
which he had spent some $2,500,000. ‘Being sat- 





- Se 
und (2) the scope of field in which they might 
be applied, Thirty-four Bentlemen accordingly 
subscribed an equal amount of money for this 
purpose privately. 

“After a careful examination of the mechant- 
cal processes we formed o partnership arrange- 
ment with Mr. Edison In his Patents, We then 
employed Beological, metallurgical and mining 
experts, and after several of us had visited Mr. 
Edison's works in America we began explora- 
tions throughout the Whole of Great Britain and 
the greater part of Europe and the northern 
Coast of Africa to determine -the most ellgthle 

:{8pot tin which to commence operations for min- 
- | ing and crushing low srace fron ores, 

“The most promising deposit that our expert 
Beologist came across was the vast ‘deposit. of 
+ [iron on the Dundertand iver, in Norway, which 
:/hus been known to metallurgists for a number 
C] of years to be the Brestest anywhere in Europe, 
. “The chief of our sclenilfic staff, Dr, Theodor 
C{ Lehmann, of Preiberg University, one of the 
+¢best: metallurgists in Europe, who had been 
conducting similar explorations for rome years, 

made elaborate horinzs, cross trenches and as- 

ays. ond shipped a large quantity of ore from 

Dunderland to Mr, Edison for trcatment. . 

~"This deposit, hag -Bitherto been commercint 

unworkabie, as lelng a trifle too lean for sil 
[ving direct to the bint furnace, although very 
rich for the purpose of crushing und concentrat- 

Ing. Another element that had farmerly barred 
+} its utilization for separating purposes was the 
t} existence of a large proportion of specular hem- 
-;atite combined with magnetite. , 
ef!) “It has only been within the Jast elght months 
“| that our codirector, Mr. Edison, has heen able 
i; ta solve the Prokiem of separating specular 
+; hematite, and as soon as we Were satisfied by 
h reports and subsequent personal obzeryations 
ef {1 Amerien that this could he accomplished and

in favor of the Edison processes, we formed 
What war practically an investigating commis. 
sion, to xo Into the matter further, because ‘if 
one-half of what Mr. Edison claimed for hls in- 
ventlons was realizavie. We were face to face 
with an industrial revolution of the Breatest and 
most far reaching magnitude. We therefore 
ought to determine (1) whether his Inventions 
were, mechanically and commerclally practicable

at a commerelal profit, we at once exercised our 
option and fnaty acquired the Norwegian prop- 
erty. We are now enabled to take two tons of 
this low grade nor-Bessemer ore and, by the 
combined ldison processes, prodtce from it over 
one ton of high grade Bessemer ore averaging 
G5 per cent of metaltic tron. 

“We have proved already on a portion of the 
Property the existence of over eighty million 
tons of iron ore, and there js reasonable hope 
for helleving that other parts of this property: 
may turn out proportionately &oad, k 
| “It is our intention at present to erect works 
and ship this ore exclusively to British. fron- 
masters, there hi Ing already a market for it at 
& superior price,” :

Reported Discovery of Color Photog- 


on raphy. . 
e Announcements of, the discovery of 
‘color photography come along with the 
same regularity and frequency tis the ‘an- 
Touncements of the discovery of perpet- 
uaj sdotlon, and they are recelved by scté 
bi $9 : 





.ffeular mode of developing and printing 
from negatives. By the use of some “se- 
cret chemical solution" the Inventor, {It 1s 
‘Jaimed, brings out the natural colors 
of the objects photographed... ... 
‘The fact that most sefentists are skep- 
tical about color photography does not 
Trove, of course, that it is a sclentific tm- ! 
possibility. Very few scientists belteved i 
that a machine could be devised that j 
Would reproduce the exact sounds of the | 
human voice until Hprsox astonished the | 
\ world with his phonograpb.. Now that i 
“we are familiar with the phonograph we : 
| marvel at its simplicity, — adele 
It is a fact, however, that the advances , 
toward color photography have been slow : 
find unsatisfactory. As carly 151810 cer- , 
ain observations were made by Dr. Sce- i 
recx of Jena which tended to encourage ! 
the view that direct color photograpby Is 
within the range of possibility. Stnee: 
that time Sir Joux Henscier, Hunt, Bee- 
gurreL, St. Victor, Porrrevin, St. Fio- 
Rest and Captain Anyey have. expert- 
mented without reaching any satlsfne- 
tory resulta... aie 
The most distinct, advance toward ac- 
tual color photography, however, was 
moadtein189}-by-Professor-Gapnien Lipp- 
Many of Paris. -He suceeeded In fixing : 
“upon the interlor of a sensitive fila the : 
‘game colors that were Possessed by the © 
“Imagen the enamera, but every attempt ; 
“made to obtain prints from the negatives. ; 
‘showing the natural colors, resulted In : 
‘tallure. The details of the discovery of 
H the Bern photographer will therefore be 
awaited with muel Interest by scientific 
men.

Mr, Reed then spoke at length, as tol- 
lows: 

Tt seems to me that this battery Is an oxecod- 
Ingly Interesting one, and I for ona feel Hke 
congratulating Mr, Edison on the results he 
has attained, ‘The battery fs Interesting 
from a chemical standpoint, belng of an on. 
tlrely different type from any of the accu. 
muldtors that has evar beon put into prac 
tical use, ‘There have been recently some 
others working In the same fleld, who havo 
produced batteries of this particular type 
but with other matorfals, not using Iron or 
nickel, but a battery of the same typo. I 
had occasion recently to examine such a 
battory and was somewhat surprised at the 
results, some of which were oxceedingly in- 
teresting, In tha partleular ease that I ro- 
fer to a battery wolghing about slx pounds 
gavo, in fts best condition, a enpacity of 80 
ampere-hours with an average electro-motlva 
forco of one volt, or somothing like 16 watt- 
hours per pound of complete coll, including 
not only the active material but the clec- 
trolyto jar and the negative conductors, 
One pecullurity in this particwar cell was 
that it showed ina inuch move marked degree 
than this battery of Mr. Edison's the success- 
ivo chemical changes which take place in that 
call. In other words, the curve instond of 
boing a curve of eharge and discharge—in- 
stead of belng stralght or being a single 
curve—was a multiple curve. ‘The charge 
curve was of this form (making a slotch on 
the blackboard), ‘The electromotive force 
here nt the beginning of the chargo heing 
about one volt, and at the end of the charge 
about two volts, ‘The discharge curve shows 
evidently that tho clectrical energy In not 
produced from uv single chemical reaction; 
that there are several chemical reactions tal- 
ing place in succession; that during the 
early part of the chargo thore Js a chemical 
change which corresponts to this part of 
the curve. When all the material has beon 
converted Into thase products, then another 
chomical reaction takes place which requires 
a higher electro-motive force, the absorption 
of more energy, and then 1 third, and in the 
process of dtscharging of course the chom- 
ical renction, which requires the absorption 
of tho grentest energy, bogina first to reverse 
and gives out the greatest energy. The 
electro-motive force drops down to this 
poiut and go on with the other two chom- 
fent reactions, One peculiarity of this cell was 
that at these polnts the electro-motive force 
actually foll down below that which [t at- 


. tained Inter, discharging In the same cur 


rent. In other words, with a uniform cur- 
rent the electro-motlye force dropped down 
to a certain point and then roso again 
slightly, then dropped down here and again 
wont below this leval, coming up again and 
going down, Now, it scems to me that a cell 
of this type is interesting particularly 
from three different standpoints. In the 
first place, an ideal battery ig one in 
which the. material will undergo as little 
motion as possible; the materinl which en- 
ters into the chomical reaction will romain 
in a certain fixed place. In any coll in which 
the electrolyte takes part In the chemical 
action and combines with the substance of 
tho electrode, that of course is Impossible; 
the electrolyte hus got continually to go Into 
and out of the olectrode, causing not only 
mechanteal disintegration but limiting the 
capacity of the cell by the quantity of the 


electrolyte. In other words, when the elec-" 


trolyte is exhausted to a certain extent the 
capacity of the cell is ended, no matter how 
much solid ,active material you muy have 
in tho olectrodes. Now, In thia type of cell 
that diMculty is oliminnted, As Dr. Ken- 
nelly has stated, all the olectrolyto that is 
needed really is onough to wet the plate, 
and the less yor have and the closer your 
plates are together the botter off you will be 
because you have less resistanea and less 
weight to carry. Anothor point whfeli, 
theoretically, is of advantage In this type of 
cell Ia that the resistanco tends to remain 
move constant. If wo have at the start two

other n metallic oxlde, the metal is a good 
conductor, the metallle oxide {s generally a 
good conductor, n much better conductor 
than maotalille sulphates in the solld state; 
fin the process of discharge of a cell of this 
lype, no matter whether these particular 
naterials are uscd or some other motals, tho 
process of discharge causes the’ metal to be 
come an oxide, the metal plates becoming 
an oxlde and the oxide plates becoming a

wo would not expect to be so grent as where 
the metal and n conducting oxide both be- 
canio ft non-conducting sulphate or other

Now, experience with the various tynes of 
Alkaline zinc-coppor batteries has shown 
that also to be the case, ‘There Is one other 
chemical rengon why this coll seems to bo 
exceedingly interesting, It may not be prac 
tlent but It polnts to the possibsuty which a 
great many of us havo been looking for, 
If wo suppose these plates to bo mado vory

from the dynamo altogether. In other 
words, when thls battery {s discharged, wo 
can take the plates out of the solution, drain 
thei off, wash out the alkali, and then we 
have got our oxygen simply reversed, trans 
ferred from one plate to the other as Dr. 
Kennelly has explained. What we want to 
do is to ravorgse those plates again. Now, 
-there are othor ways besides electrochem-

example, wo have in this particular battery, 
assuming this to be the correct formula, 
nickel hyperoxide, as it is called in the 
paper, to start with, In metallic fron In a 
finely divided state the discharge of that 
battery would naturally result in the pro- 
duction of forrous oxide first. That would 
be the first stop at least, 

Whethor that would be final or not I 
would not want to say. And the final step 
in this would certainly bo the production of 
nickel monoxide, It might not be tho first 
stop. It might he, as Dr. Kennelly has said, 
the production of piekel peroxide Ni, Oy. 
But metallic fron would certainly not reduco 


the nickel oxide to any lower degree, In 
“ther words, it would not produce metallic 
1 ‘el unless the electro-motive force dropped 
(4 to something like four or five hun- 
ad dts of a volt. The chomleal relation 





660 


between the forms of nickel monoxide and 
forrous oxide ts very little, I think the 
nickel monoxido Is 61 and a fraction calories 
and the ferrous oxide 68 and a tractlon-- 
about G9, But supposo wo have this battery 
in a discharge state; In othor words, this 
nickel hyporoxide is reduced to nickel 
monoxide; metallte tron !s oxtdized to fer- 
reous oxide and we havo tho plates cleaned 
from Impuritios, It js a wall-known fact 
that ferrous oxide can bo converted back 
Into metallic fron by simply heating {t to 
about 300 degrees in the presence of hydro. 
gen, and {t can he done with carbon 
monoxide. Wo can also find other ways by 
a dry process or a thoromochemical process 
of producing poroxide, I do not mean to 
say that we can produce this particular one, 
but I am speaking now in genoral of this 
type of battory. I do not mean to Bay that 
wo could do this actually with these par- 
ticular substances, With iron I think it 
would be very plausible that that might bo 
necomplished, But suppose we succecd (1 
working out @ process for dofng both, Thon 
we can charge this battery without the ust 
of any dynamo or any electric current, $n 
other words, the battery Js not only a storage 
battery but It is an Instrument for trans- 
forming hent and chomical energy fromm 
other sources such os carbon, possibly cr: 
hon monoxide or hydrogen, into electricnt 
enorgy. Now ‘that, of course, would not he 
a direct process—an indirect process 9° 
getting olectrical energy, possibly, out ot 
errbon; yet it might be a very oconomica! 
process. [ think, therofore, that a cell «i 
thls type is interesting trom these thre: 
reasons particularly, In regard to the es- 
pacity of a coll of this kind, I made a rough 
calculation of the relative ampere-hour 1:. 
pacity of tho active material considered [1 
itsolf, without reference to the wolght of 
electrodes or the olectrolytes of the ern 
taiiing-cells, which may be Interestin: 
In the caso of tho lead cell, wher 
a lend sulphate ts formed in dtacharr 
on both electrodes, thero would i 
theoretically a total capacity of 44 ampore- 
hours, about, to the pounu of actlye ma + 
torial, constdering botn plates, providing 
was all utilized. In this coll there would : 
about 160 ampere-hours theoratically to the 
pound of active material, Now, 1 do not: 
any particular reason in the abstract w', 
We should not be able to actually utilize u- 
high a percentage of the total active mi- 
torial in this cell ns in the load cell. In fae. 
it seems to me that we might utilize a hight» 
percentage from the very nature of thi: 
cell, that the products formed by discha:. 
are not non-conductors, as in the case of t-. 
lead cell, Ono of the reasons why wo enn 
only utilize a small percentage of the nr 
torial in the lead coll ts that the product .. 
discharge is # non-conducting substan. 
which obstructs the current; whereas in 
this case the products on both electri.’ 
remain the conductors, and the only 1: 
ference being that the metallic constituen:. 
and the oxidized metal change places both }.. 
charge and discharge. (Applause.)
